金属橡胶隔振器具有非线性的动力学特性,对这种迟滞阻尼隔振器进行建模研究,建立了参数有物理意义的动力学模型.根据单自由度性能试验,进行了有关参数的试验识别方法研究,应用能量法及最小二乘法将非线性方程组转化为关于参数的线性方程组,从而对金属橡胶隔振器参数进行识别.识别结果与实验结果有较好的一致性,识别结果也说明了结构参数对隔振器性能的影响.
The metal rubber vibration isolator has nonlinear dynamic characteristics, modeling the hysteresis damping vibration isolator and establishing a dynamic model with parameter significance.According to the single degree of freedom performance test, the related parameters were tested Identification method, applying energy method and least square method to transform the nonlinear equations into linear equations about the parameters, so as to identify the parameters of metal rubber vibration isolator.It is found that the identification results are in good agreement with the experimental results, and the identification results It also shows the influence of structural parameters on the performance of vibration isolators.
