When installing an active damping system to practical ram-type milling machines, the available locations are limited due to the space constraints and the interference against machining processes. Therefore, it is often the case that the non-collocated configuration of the active damper becomes inevitable. Such non-collocated active damping system (NCADS) may require high force–density actuators to compensate the poor controllability, and right half-plane zeros caused by the NCADS make it challenging to maximize the active damping performance while securing the controller stability. In addition, the different vibration characteristics during the rough- and finishing-milling require the vibration control strategies adapted to the machining operations. We propose the sensitivity function shaping methods in NCADS for high-throughput operation of both rough- and finishing-milling. Using the proposed method, we increase the dominant-mode dynamic stiffness of the ram structure by 154% for rough-machining operations, and thereby increase the chatter-free cutting depth up to 3.5 mm. Also, in the high-speed finish-milling test, we reduce the retainer vibration by 58% and thereby suppress the associated beating mark on the surface profile, achieving the surface roughness reduction by 40%. The results validates the high-throughput machining performance of the proposed vibration suppression control methods in both rough- and finishing-milling.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"616 ","pages":"Article 119205"},"PeriodicalIF":4.3,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144185433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The equations of motion are derived using a variational approach and solved with the method of multiple scales to analyze primary, parametric, and combination resonances. The findings reveal that in the absence of electromagnetic excitation, the symmetrical and asymmetrical systems exhibit hardening nonlinearities with negligible backward mode amplitudes. As the electromagnetic parameter increases, softening nonlinearities dominate, activating both forward and backward modes and introducing new solution branches. The importance of defining multiple detuning parameters is underscored, as this enables the capture of forward and backward amplitudes and new solution branches, which are otherwise unattainable. The study further reveals that shaft and disk eccentricities significantly influence system behavior. In the absence of shaft eccentricity, symmetrical systems exhibit simpler dynamics without backward amplitudes, while asymmetrical systems retain their dynamic richness, including stable and unstable solutions, jump phenomena, and new branches rooted in backward modes. The findings highlight that symmetrical systems are more sensitive to shaft eccentricity, while asymmetrical systems, driven by parametric excitations from shaft asymmetry, exhibit resilience to such changes. Additionally, the electromagnetic field's phase plays a crucial role in shaping higher stable solutions, with minimal impact on lower amplitudes. As the electromagnetic parameter increases, the system transitions from harmonic responses to multi-harmonic, quasi-periodic, and chaotic behaviors. These insights provide a comprehensive understanding of rotor dynamics under combined excitations.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"617 ","pages":"Article 119240"},"PeriodicalIF":4.3,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144222635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dynamic coupling of the space flexible-link manipulator is decomposed into the coupling between the rigid motions of the base and link, and the coupling between the rigid motion and the flexible vibration according to the SP theory. The dynamic coupling between the base and the link is used to adjust the position and attitude of the base and the link vibration is reduced based on the coupling between the rigid motion and flexible vibration. According to SP theory, the rigid motion of the base is approximated by its quasi-steady state value. A low frequency vibration around quasi-steady state value of link vibration is obtained and used to approximate the dynamic behavior of link vibration within fast time scale. On this basis, two novel objective functions of minimizing vibration during motion and residual vibration are constructed. Since the calculation of high-frequency vibration is avoided, the efficiency of the trajectory optimization method is greatly improved. Particle Swarm Optimization (PSO) algorithm is adopted to realize multi-objective optimization.

In this situation, it is crucial to maintain a good damping effect of the TMD damper on a main structure. To achieve this goal, this paper develops a new nonlinear TMD damper to suppress the vibration of the frame structure, in which the mass block is connected to pre-stretched superelastic SMA springs and equipped with a displacement-limit device. This new TMD damper fully utilizes the energy dissipation advantages of both the pre-stretched SMA springs and the displacement-limit device attached with an additional viscoelastic material. At first, the motion equation of the structure attached with the new nonlinear TMD damper is established and the mechanical model of the frame system is verified by shaking table tests. Afterwards the parameters of the displacement-limit device and the pounding gap are optimized through minimizing the discrepancy between the mean value of maximum input energy in the structure with the new damper and that with the TMD damper equipped with only the SMA springs. During the optimization, the pounding force is restricted to an acceptable value. The numerical results show that the control performances of the new nonlinear damper and the TMD damper with only the pre-stretched SMA springs are almost the same. No matter which TMD damper is used, the identical input energy will lead to the same peak responses of the frame. Compared with the pounding TMD, because of the replacement of the linear steel springs with the pre-stretched SMA springs, the proposed damper can increase the reduction ratio of peak responses by 16.4 % in some cases. And the maximum impact force on average is reduced by about 33 %, which is significant to protect the displacement-limit device.</div></div>","PeriodicalId":17233,"journal":{"name":"Journal of Sound and Vibration","volume":"616 ","pages":"Article 119214"},"PeriodicalIF":4.3,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144178726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
