在阻尼弹性减振器设计计算中采用的双扭摆模型具有直观简单的优点,然而所求得的减振器参数并非最优,必须进行一些修正. 本文对带有减振器的多自由度系统进行模态分析,利用正则坐标模型得出阻性尼弹性减振器最佳调谐以及相应的减振器参数的计算公式,所得结果较双扭摆模型为佳. The double-torsional pendulum model used in the design of damped elastic dampers has the advantages of being intuitive and simple, however, the obtained parameters of the dampers are not optimal and some modifications must be made.In this paper, the multi-degree of freedom system with dampers The modal analysis is carried out, and the optimal tuning of the resistive nylastic vibration damper and the corresponding formula of the damper parameters are obtained by using the regular coordinate model. The results obtained are better than those of the double torsion pendulum model.
