摘要
首先以策动力频率为自变量,分析了受迫振动中速度共振频率下阻尼力以及策动力和回复力3个力所做功的特征,然后以阻尼系数为自变量,分析了小于或大于速度共振频率时阻尼力所做功与阻尼系数的依赖关系,从而对受迫振动中共振现象有了更深入的认识.
In this paper, the characteristics of the works done by the damping force, driving force and restoring force under the velocity resonance frequency in forced vibration are analyzed with the driving frequency as the independent variable, and then the dependence of the work done by the damping force on the damping coefficient is analyzed with the damping coefficient as the independent variable when the vibration frequency is less than or greater than the velocity resonance frequency, so as to have a deeper understanding of the resonance phenomenon in forced vibration.
