In this paper, squeal noise is reduced by means of liner modification with different width and depth of the liner slot. Effect of change in liner geometry on squeal noise reduction is studied analytically and verified experimentally. A full nonlinear perturbed modal analysis is used to find the stability of the system. In order to validate the analytical results, experimental tests are carried at a certain slow speed having low brake pedal force. The experimental results show that the drum brake squeal noise is found to be reduced by a significant amount by applying the proposed method. It is found that significant modification in geometry of liner in view of noise reduction is not affecting much the vehicle performance.","PeriodicalId":34979,"journal":{"name":"International Journal of Vehicle Noise and Vibration","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66688935","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 sensitivity of primary and secondary suspension parameters on ride and stability is analysed independently. Finally, suitable suggestions are given for primary and secondary suspension parameter values to obtain improved lateral ride and stability.","PeriodicalId":34979,"journal":{"name":"International Journal of Vehicle Noise and Vibration","volume":"187 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66688559","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 present article, in order to bring a reliable methodology for monitoring and diagnosis of rotating machinery failures, a test rig is implemented. However, to diagnose gears and bearings combined faults, a monitoring system based on neural network model (NNM), is proposed. To train and test the NNM, the principal high frequency indicators, determined with the collected time domain vibration data, and codes of defects are used respectively as input and output data. A comparison of two learning algorithms, optimised by the Taguchi method, was done to determine the best NNM. Therefore, the proposed method is effective to study other various industrial cases.","PeriodicalId":34979,"journal":{"name":"International Journal of Vehicle Noise and Vibration","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66688877","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 this research, a quarter car model was subjected to International Standards Organization (ISO) random road profile with a pothole and a speed bump in order to obtain the ride quality and the reaction forces occurring at the ball joint. After classifying three ride qualities, another simulation was conducted on this model to study the stress distributions, in which the ball joint and its socket were treated as flexible bodies. Finally, based on the results of the FE analysis, fatigue life of the joint was measured for each ride quality. Based on the findings, it was concluded that a good ride quality has an adverse effect on the fatigue life of the ball joint component. ANSYS Workbench and CATIA V5 were used for modelling and simulation.","PeriodicalId":34979,"journal":{"name":"International Journal of Vehicle Noise and Vibration","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66688946","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}

This paper focuses on developing the methodology for predicting in-cab noise and tactile vibration on steering wheel and driver seat rail for operational WOT load case. The vibro-acoustic simulation was performed using FEM-FEM method with fully coupled approach. The process was divided in three sections: first, prediction of input excitations forces by MBD model, secondly applying these forces to FE model to predict noise and vibrations, thirdly weak point analysis, optimisations and iterations for the peaks which are not meeting targets. Weak point analysis includes transfer path analysis (TPA), panel contribution analysis (PCA) and operational deflection shape (ODS) to understand the weak points of the structure. Weak points are identified using virtual TPA to show the correlation with weakness of frame lateral stiffness. The countermeasures worked out upfront in virtual validation stage to improve the weak points and design changes are implemented in the final design. The overall process helped to meet first time right with 40 kg weight saving. Further the established process was followed for rest of the truck projects.","PeriodicalId":34979,"journal":{"name":"International Journal of Vehicle Noise and Vibration","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66688629","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 stress distribution is evaluated and the location of the neutral axis of the FG beam is obtained. Different types of attachments connected to the beam at specific locations are analysed. The effect of using FG materials to enhance the properties of the beam, resulting in a decreased response of the beam, is made clear.

Various isolation techniques including passive, active, or semi active have been proposed for achieving best noise and vibration attenuation. Discrete and distributed mathematical models have been employed to predict the dynamic response of EPS systems.

This research shows an experimental application for the detection of bearing defects at two stages of degradation: at the early stage and at an advanced stage. In this work, a comparative experimental study between vibratory and acoustic emission measurements, analysed by VMD, is carried out. However, the application of this method requires determining the number of significant frequencies (K) and a balancing parameter (α). For this purpose, the operational modal analysis (OMA) and a correlation study are used to determine the required parameters K and α. The results show that both measurement methods work well to detect the bearing frequencies, but the vibration measurement was more sensitive for an early detection.","PeriodicalId":34979,"journal":{"name":"International Journal of Vehicle Noise and Vibration","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47296469","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}
