摘要
干摩擦隔振系统的阻尼值决定着系统的响应情况。运用试验测试和理论仿真相结合的方法,将阻尼值根据频率分成多个不同的频段,并用优化方法获得不同频段的阻尼值。该方法所得到的等效阻尼值与能量法获得的阻尼值相近,为干摩擦阻尼隔振器等效阻尼的确定寻找一种新的有效方法。
The damping value of dry friction vibration isolation system determines the response of the system.In this paper,a method combining experimental tests and theoretical simulation is used to divide damping value into multiple frequency bands according to frequency and obtain the damping values at different frequency bands by optimization.The equivalent damping value obtained by this method is similar to the damping value obtained by energy method.This is a new and effective way to obtain equivalent damping of dry friction vibration isolation.
