摘要

根据橡胶动模量和刚度的实验结果,拟合出隔振器刚度随频率的变化关系式,并通过隔振器的动、静刚度确定其待定系数。在传统四端参数法的计算中计入了刚度的频散效应,以提高橡胶隔振器阻抗计算的准确性。同时设计了一种基于纯加速度测量的阻抗测试方法并对两型隔振器进行了阻抗测试,由实测数据与不同刚度假设下的计算结果比较可见:计入刚度频散效应后的隔振器阻抗计算更精确,而基于加速度测量的阻抗测试是可行的。

Abstract

The relationship between stiffness of isolators and vibration frequency is deduced according to testing result of rubber’s Young's modulus and stiffness, and isolators’ static stiffness and dynamic stiffness are used to determine relevant coefficients. Stiffness dispersion is brought into theoretical estimation of rubber isolators based on four-polar parameter equations for higher accuracy.On the other side, an impedance testing method based only on acceleration measurement is designed and two types of rubber isolators are tested in this method. By the comparison of testing results and estimation results under different stiffness modes, it is concluded that impedance estimation is more accurate with stiffness dispersion considered and the test based on acceleration is feasible.
