【摘要】 针对附加多个动力吸振器的多自由度振动系统,本文利用结构导纳理论,引入附加动力吸振器后振动系统的等价结构导纳,推导了系统的功率流表达式,揭示了系统功率流的传递特性。并探讨了以功率流为控制量进行单个或多个动力吸振器优化设计的方法以及主振系的阻尼特性对系统功率流和吸振器优化设计的影响。更多还原

【Abstract】 For a multiple degrees of freedom vibration systems with dynamic vibration absorbers (DVAs), the expressions of the power flow input each part of system were educed on the basis of structure mobility theory and an equivalent mobility of the system attached DVAs in this paper. Furthermore, the transmission characteristics of the power flow of the system were revealed. Finally, an approach to the optimum design of a DVA or multiple DVAs was proposed in which the power flow was made the objective function.更多还原
