摘　　要：通过弹簧 质量 刚杆 阻尼器系统模拟了扭振阻尼减振系统 ,提出利用功率谱函数识别系统阻尼的方法 ,并通过有关实验对阻尼器的阻尼特性及其温度效应进行研究 。Via a spring-mass-rigid rod-damper system, the designed and experimental ques tions of the rotational silicon oil damper was studied in the paper. Using the above single free degree system, the torsion damper system is simulated, and p arameter identification method with power spectrum density function was given. T he damper characteristic and temperature effects are given out. Finally, the non linear feature of the damper was discussed.
