摘要
研究了非对称弹性粘性阻尼滞迟隔振系统动力学模型的参数识别方法,该模型中弹性恢复力与位移变形之间存在非对称关系。采用电液伺服材料试验机加载方式,通过位移控制,运用滞迟回线分解法及最小二乘法识别模型参数。通过仿真试验可以看出,该方法简单,方便,具有实际可行性。
The parameter identification of dynamic model of hysteretic vibration isolation system with unsymmetrical elasticity and viscous damping is studied,in which the relationship between the elastic restoring force and deformation is unsymmetrical.Electro-hydraulic pressure material test-bed is used to give load to the elastomer.By using displacement control,the method of hysteretic loop decomposition linking with least squares method is adopted to identify parameters of the model.The simulative examination indicates that the method is simple,convenient and feasible.
