摘要
本文研究被动减振装置的优化设计问题。对经受稳态激励的振动系统提出了一个两步减振优化设计方法,以确定减振装置的最优安装位置和参数。该方法直接以对系统的振动量级要求为设计目标函数,避免对原始结构和附加减振结构组成的复杂系统进行重复的动态性能分析,因而可用于工程中复杂结构的减振设计。
This paper is mainly engaged in optimal design of passive vibration reduction(V--R) devices. The two-step optimal method for the vibration system subjectto steady excitations are presented in the paper so as to decide the optimalinstalling positions and parameters for V-R devices. The method directly takesrequirement to system vibration levels as objective function and avoids repeateddynamic analysis to the system composed of original structure and added V-Rdevices, which makes it applicable to V-R design for complex structure in engin-eering.
