摘　　要：对一种新型电磁-碰撞复合阻尼系统展开研究。提出碰撞力模型描述碰撞过程,采用等效黏性阻尼表示电磁阻尼,建立电磁-碰撞复合阻尼系统动力学模型,通过试验验证了该理论模型的正确性。对电磁-碰撞复合阻尼系统的动力学特性进行分析,并研究了不同激励条件下该系统的减震效果。Here,a new eddy current-pounding composite damping system was studied.A pounding force model was proposed to describe collision process,the equivalent viscous damping was used to represent eddy current damping,and the dynamic model of the eddy current-pounding composite damping system was established.The correctness of the theoretical model was verified using tests.Its dynamic characteristics were analyzed,and the vibration reduction effect of the system under different excitation conditions was studied.
