摘要

提出了一种用于控制特殊多方向强迫振动的滚珠式动力吸振器。通过理论分析和数值计算，研究了该吸振器的振动控制机理和主要参数对吸振效果的影响。利用定点理论，优化设计了控制系统的最优频率和最优阻尼。研究表明，利用该结构简单的吸振器可以有效地控制机械或结构在共振频率点附近所发生的特殊的强迫振动响应。

Abstract

A dynamic vibration absorber with ball is presented to control the special multi-direction forced vibra-tion. Based on the theoretical analysis and numerical calculation, the mechanism and the effects of parameters of vibration control of the absorber are clarified. According to fixed-points theory, the frequency and the damping of vibration control system are optimized. The results show that the special forced vibration at resonance point of machine or structure can be reduced effectively by using this simple ball type dynamic vibration absorber
