摘要

基于导纳功率流理论建立了变截面阻尼复合梁式新型宽带吸振器吸振分析理论模型,以输入被控制结构净功率峰值最小为目标函数,运用混沌粒子群算法对吸振器参数进行了优化,并给出了吸振效果较好的参数分布范围。结合实验结果表明:通过混沌粒子群算法优化后的得到的变截面阻尼复合梁式新型宽带吸振器具有好的吸振效果。

Abstract

Vibration model of new type of broadband dynamic vibration absorber, which is a composite beam with rubber layer in variable cross-section, coupled with plane is established by theory of power flow. While the minimize of the maximum peak of pure power flow input to structure which is controlled by absorber is specified as goal function, particle swarm optimization is used to optimize the parameters of broadband dynamic vibration absorber, then scale of the parameters of dynamic vibration absorber which greatly decrease the vibration of target structure is summarized. After comparing with the results of experiment,conclusion is obtained and shows that particle swarm method is suitable for analyzing the complex continuous absorber optimization.
