However, maintaining effective resonant behavior by tracking the resonant frequency can be challenging due to load fluctuations. This study introduces a software-based phase-locked loop (SPLL) control method for three-degree-of-freedom acoustic resonant systems (3DOFARS). Initially, the dynamic equation governing the behavior of 3DOFARS is provided, followed by a frequency domain analysis based on the amplitude-phase frequency characteristic curve. Subsequently, the SPLL control method is developed by considering the phase relationship between the system’s excitation signal and response signal, and a control model is then established using Simulink. For the step, slope, and sinusoidal disturbances with specific amplitude and frequency variations, the SPLL control method can track the excitation frequency to the resonant frequency in real time. Among these disturbances, step disturbances pose a greater risk of system instability compared to slope and sinusoidal disturbances. Finally, simulation verification and statistical analysis are carried out by introducing quality interferences of varying types, amplitudes, and frequencies to assess the SPLL control method’s impact on different interferences. Under stable conditions, the SPLL method has better control capabilities against low-frequency interference and better robustness against high-frequency interference. In comparison to conventional methods, the SPLL control method effectively maintains real-time tracking of the excitation frequency to the resonant frequency while upholding process flow integrity.","PeriodicalId":508293,"journal":{"name":"Journal of Vibration and Control","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141341453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Owing to the complicated constitutive relationship and nonlinear geometric deformation, it is difficult to accurately predict the dynamic characteristics of CCPCs using the finite element method (FEM) or theoretical methods. In this study, we employed a nonlinear autoregressive with exogenous input (NARX) artificial neural network (ANN) to identify the dynamic model of the CCPC under an impact load, using data from over 100 experiments and numerous accumulated samples. The corresponding experimental data for the CCPC were used to train the ANN and determine the rational ANN model. The identification results indicate that appropriate number of neurons and time-delay orders can effectively reduce the identification errors. Compared with the response predicted by the FEM, the identification model can describe the nonlinear characteristics emerging from phononic crystal (PC) experiments more accurately. This study provides an efficient and accurate online identification approach for PC-modeling.","PeriodicalId":508293,"journal":{"name":"Journal of Vibration and Control","volume":"90 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141342328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the case of a railway vehicle, it is possible to increase comfort using S/A control of vertical or lateral secondary dampers. On another way, S/A control offers the possibility of solving a contradiction in the damping requirements for different driving modes, in the case of control of bogie yaw dampers. However, this case has not yet been sufficiently investigated. This paper deals with applying magnetorheological dampers with semi-active control in the locomotive bogie to reduce hunting oscillation. The magnetorheological bogie yaw damper design, new algorithms for its control and application on a complex multi-body locomotive model that simulates fast running on a real straight track are shown. An essential part of the paper focuses on the effect of the damping force level and damper force transient response time. The results have shown that using the semi-active control of the yaw dampers makes it possible to reduce vehicle body lateral oscillation by 60% and improve running stability for higher equivalent conicity and subcritical speed. The critical speed can be increased by more than 250 km/h. The efficiency of the proposed semi-active control increases with increasing damping force level and decreasing transient response time. The control is most effective under conditions of low equivalent conicity.","PeriodicalId":508293,"journal":{"name":"Journal of Vibration and Control","volume":"33 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141346220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a novel motion planning method, aimed at maximizing robustness to model uncertainties and based on a direct formulation, is proposed and tested. The choice of a direct formulation is aimed at overcoming the numerical problems often encountered when dealing with indirect trajectory planning methods, including the limited robustness to any model-plant mismatch. The proposed direct method is based on three different motion profiles, and is tested for the rest-to-rest motion of a slender beam, with and without parametric robustness constraints, but the same framework can be adapted to countless other situations and formulations. The experimental results showcase good accuracy and a sensible improvement in mitigating the effects of unmodeled perturbations on the system sported by the proposed robustified method over its non-robust counterpart. Experimental results show also the outcome is very similar to the one resulting from a more numerically challenging solution formulated as an indirect problem by means of a two-point boundary value problem.","PeriodicalId":508293,"journal":{"name":"Journal of Vibration and Control","volume":"38 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141345846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In helicopters, vibration is a phenomenon inherent to their operation, and although cannot be eliminated, must be minimized to acceptable levels of safety and comfort. In this context, this paper aims to present the design, testing, and dynamic behavior of a new device entitled smart pitch link, a device with superelastic material for passive vibration control. The paper depicts the design process, assembly, and device testing using a whirl tower that simulates a helicopter rotor in hover. The approach adopts a comparative analysis of the dynamic response on the prototype in reference condition, with a stiff pitch link, with the modified prototype, and with the superelastic pitch link installation. In addition, beyond hover tests, cyclic commands and an asymmetrical lateral gust were employed to observe the output response of the device under transient loadings. Contrary to the literature data about the low time response of SMA, the device presents satisfactory time response and attenuation in frequencies close to main rotor frequencies, with signal attenuations between 2 to 4 dB without any external energy consumption, which, in a comparative analysis, may exceed more than 50% of vibrational amplitude attenuation.","PeriodicalId":508293,"journal":{"name":"Journal of Vibration and Control","volume":"92 14","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141352592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary objective is to enhance ride comfort and ensure vehicle stability by addressing the divergent needs of vibration control. The research identifies key issues in existing optimization algorithms, namely, the exploration stage inefficiency in Big Bang Big Crunch Optimization (B3C) and the slow convergence rate in Coyote Optimization (CO). To overcome these challenges, a novel hybrid algorithm, Hybrid Coyote optimization based Big Bang Big Crunch (HB3C), is proposed. The research objective is to optimize the LQR weighting matrices using the HB3C algorithm, aiming for improved ride comfort and vehicle safety. The problem statement involves the inadequacies of existing algorithms in addressing the exploration and convergence issues. The motivation lies in enhancing the efficiency of VASS through optimal control, leading to better ride comfort and safety. The methodology involves integrating CO within a loop with B3C to compute the optimum reduction rate for the algorithm. Since, B3C algorithm’s success is highly dependent on selecting the ideal reduction rate. This hybrid approach is then applied to optimize the existing LQR weighting matrices. The results are evaluated in terms of time domain and frequency domain response analysis, with a focus on ride comfort based on ISO 2631-1 standards. The study demonstrates a maximum reduction of approximately 74% achieved by the optimized HB3C-LQR controllers.","PeriodicalId":508293,"journal":{"name":"Journal of Vibration and Control","volume":"4 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141363457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the influence of vibration on tunnel surrounding rock and support structures during the blasting process cannot be ignored. In this study, based on the background of tunnel blasting construction, we theoretically analyze the reasonable range for selecting the optimal delay time, considering the wave superposition cancellation effect and rock fragmentation effect. We use field measured single-hole waveform and calculate superimposed predicted waveforms for different delay time through linear superposition. This allows us to determine the optimal delay time; it is then validated through numerical simulation and field experiment. The results indicate that, based on the principles of interference vibration reduction and rock fragmentation, the optimal delay time in theory should be in the range of 6.14–8.06 ms. By performing superposition calculation on the measured single-hole waveforms, we determined that the optimal delay time for continuous detonation of cut-holes is 7 ms. The delay time of 7 ms falls within a reasonable millisecond range and it is consistent with the results of numerical simulation. When the optimal delay time was applied to field blasting, the measured vibration waveforms exhibited uniform distribution. Compared to blasting without delay, the peak vibration velocity of the cut-holes decreased from 2.08 cm/s to 0.20 cm/s, and the dominant frequency band shifted from 20 Hz–60 Hz to 30 Hz–120 Hz. This achieved the desired effects of reducing vibration and enhancing frequency. These findings can serve as a reference for future similar engineering projects.","PeriodicalId":508293,"journal":{"name":"Journal of Vibration and Control","volume":"101 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141361333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At present, the data-driven method has been successfully applied in the field of bearing RUL prediction. However, the feature correlations between data at different moments may be different, few methods can dynamically identify the change of the feature correlations between input data at different moments, which can impact the performance of the prediction. This article proposes an innovative RUL prediction method based on the adaptive feature correlations aggregation module (AFCA) and gated recurrent unit (GRU) to address this issue. First, statistical features are extracted from the vibration signal, and the fully connected graph is constructed to map the vibration signal data into the graph structure. Subsequently, the AFCA module is designed and constructed, and the AFCA-GRU model is built by combining GRU. A series of constructed fully connected graphs are fed into the model, and the hidden degradation information in graph structure data is mined to realize the prediction of bearing RUL. Among them, AFCA is used to adaptively explore the spatial correlations between graph node features at different moments, and GRU is used to explore the temporal correlations between graph structures. The PHM2012 Challenge dataset is utilized to validate the effectiveness of the proposed method. The comparative experimental results demonstrate that the performance of the method proposed herein surpasses that of other data-driven methodologies, with the capability to accurately predict the RUL of bearings.","PeriodicalId":508293,"journal":{"name":"Journal of Vibration and Control","volume":" 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141369535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
