为了实现对含有橡胶隔振器的机械系统的建模和动力学分析，对隔振器的迟滞阻尼特性识别方法进行了研究。首先，对橡胶隔振器进行了正弦振动试验，获得不同频率，不同振幅下恢复力和位移之间的关系。接着，根据阻尼在一个振动周期内耗能相等的原则，把恢复力分解为弹性力和阻尼力，采用变刚度变阻尼法分别对不同频率下的弹性力和阻尼力进行了参数识别，获得了弹性系数和阻尼系数与振动频率之间的关系。然后，采用参数识别的结果，应用“大质量法”对含有橡胶隔振器的空心轴结构进行了建模和动力学分析，获得了质心位置响应加速度随频率变化的曲线。响应加速度的最大值为11.79g(100Hz)。最后，对整个结构进行了正弦振动试验并把响应加速度曲线和相应的振动试验结果进行了对比分析。试验结果表明：计算的响应加速度最大误差为9.2%；可以满足工程计算精度的要求。证明了这种参数识别方法的正确性，应用这种方法可以使橡胶隔振器建模和分析过程统一化和规范化。

In order to realize modeling and dynamic analysis of a mechanical system containing rubber isolator, a parameter identification method of rubber hysteresis damping is investigated. Firstly, sine vibration test of rubber isolator is conducted so as to acquire the relationship between resilience force and displacement in different frequencies and amplitudes. Secondly, according to the principle of damper dissipation same energy in one vibration period, the resilience force is broken into spring force and damping force, which can be identified by a new approach called variable-rate stiffness and damping parameter identification. The relationships of elasticity coefficient and damping coefficient with variation of frequency would be obtained by this parameter identification method. Then, the above mentioned parameter identification results are applied into modeling and dynamic analysis of a shaft structure including the rubber isolators. ‘A big mass method’ is also used in the process of calculation response acceleration curve with variation of frequency at the position of centroid. The most acceleration reaches 11.79g at frequency of 100Hz. Finally, the sine vibration test of the whole structure is carried out and the distinctions of test result and calculation result are carefully compared. Experimental results indicate that the max error of calculation result is up to 9.2%, which has satisfied the requirement of engineering calculation. It has proved that correctness of this parameter identification method. Furthermore, application of this method will make the process of modeling and analysis of rubber isolator unification and standardization.
