振动台上冲击消振器垂直双面冲击运动研究

Research on the Vertical Two-sides Impacting Motion of Impact Damper on Vibrating Table

冲击消振器是一类结构简单、应用较广的消振器,但其设计迄今仍主要靠反复试验。本文对固定在简谐振动台面上的冲击消振器垂直双面冲击运动进行了理论与实验研究。结果表明:本文的理论分析可靠,从而为用两步法建立一类垂直振系的实用冲击消振理论奠定了基础。

Impact damper ia a kind of damper with simple structure and wide application,but now it is still de- signed by repeated tests.This paper discusses about the impact motion of vertical two-sides of an impact damper fixed on a simple harmonic vibrating table theoretically and experimentally.The results show that the theoretical analysis is reliable,so a base of setting up pratical impact damping theory of vertical vi- brating systems by the two-steps method is thus established.
