随机激励下动力吸振器参数优化方法
One method for optimizing vibration absorber parameters under random excitation
摘要
Abstract
By taking a two-degree-freedom vibration system for example,this paper made the summation of response amplitude of the primary vibration system under different frequency as objective function,used the appropriate optimization method to choose and optimize dynamic vi-bration absorber parameters;and by working out and analyzing the frequency domain and time -domain response of vibration system,this paper contrasted the effect of different frequency in-tervals.The results showed that the smaller the frequency intervals are,the better the effect of the DVA is;but the effect of DVA will not change obviously when the frequency intervals are too small.By optimizing the parameters of a two-degree-freedom vibration system and analyzing the results,this paper elaborated a thought that can be used to the optimization of parameters of complicated multi-degree-freedom vibration system,offered a practical and effective method for optimization of Vibration Absorber parameters under random excitation.关键词
