Abstract

This paper presents the modelling and identification of hysteretic behaviour in a Vacuum Packed Particles Torsional Damper (VPPTD) filled with ABS (Acrylonitrile Butadiene Styrene) polymer granulate. The presented device is an innovative member of the semi-active damper family, featuring real-time controllable damping characteristics. A series of experiments were conducted to observe the response of the damper under various loading conditions. The Modified Bouc–Wen model (MB-W) was employed to capture the non-linear hysteretic characteristics exhibited by the damper. Using an evolutionary algorithm, the parameters of the model were identified on the basis of experimental data. The identified parameters of the Modified Bouc–Wen model are described by underpressure functions. The proposed model was validated, demonstrating its efficacy in predicting the damper’s hysteretic behaviour under various operating conditions. This study contributes to the understanding and prediction of complex non-linearities in VPPs.

真空填充颗粒扭转阻尼器滞回建模与辨识

本文建立了以ABS（丙烯腈-丁二烯-苯乙烯）聚合物颗粒填充的真空填充颗粒扭转阻尼器（VPPTD）的滞回特性模型和辨识方法。该装置是半主动阻尼器家族的创新成员，具有实时可控的阻尼特性。通过一系列试验，观察了阻尼器在不同加载条件下的响应。采用修正的Bouc-Wen模型（MB-W）捕捉阻尼器的非线性滞回特性。基于实验数据，采用进化算法对模型参数进行识别。修正的Bouc-Wen模型的辨识参数用欠压函数来描述。所提出的模型经过验证，证明了其在预测阻尼器在各种操作条件下的滞回行为方面的有效性。该研究有助于对vpp复杂非线性的理解和预测。

期刊介绍： The Journal of Sound and Vibration (JSV) is an independent journal devoted to the prompt publication of original papers, both theoretical and experimental, that provide new information on any aspect of sound or vibration. There is an emphasis on fundamental work that has potential for practical application. JSV was founded and operates on the premise that the subject of sound and vibration requires a journal that publishes papers of a high technical standard across the various subdisciplines, thus facilitating awareness of techniques and discoveries in one area that may be applicable in others.
