波纹管式复合阻尼隔振器设计与力学特性研究
Design and mechanical properties study of bellows-type composite damping vibration isolator
摘要
Abstract
A new type of bellows-type composite damping vibration isolator was designed to address the complex structure and poor sealing of the bellows vibration isolator and the metal rubber composite vibration isolator.Static mechanical tests were carried out on different parameters affecting the vibration isolator.The mechanical properties were characterised using average stiffness,energy dissipation,and structural loss factor.The results showed that the addition of metal rubber and dimethyl silicone oil significantly enhanced the mechanical properties of the vibration isolator and the performance increased with the increase in the density of metal rubber.At 4 mm displacement loading,the annular metal rubber enhanced the vibration isolation performance significantly.As the loading displacement increases,the energy dissipation and structural loss factor increase continuously,while the average stiffness shows a slightly decreasing trend.Finally,based on the equivalent damping model of the trace method and considering the rules of change,such as density and deformation amplitude,a static mechanical model was constructed using the parameter decomposition identification method,with stiffness prediction error of less than 1.5%.关键词
