引言许多实际的机械系统可以简化为一个单自由度系统,因此,单自由度系统的减振问题已引起了人们的关注。由于对原系统进行修正往往是不切实际的,所以通常采用的方法是增加一个辅助(减振)系统,以抑制原系统的振动。本文考虑了在给定激励频率下线性阻尼系统减振器的优化设计问题,并对数值最优化结果进行了讨论。系统动力学如图1所示,系统2附于系统1,整个系统的动力方程可表示为: INTRODUCTION Many practical mechanical systems can be reduced to a single degree of freedom system. Therefore, the problem of damping of single degree of freedom system has attracted people’s attention. Since it is often impractical to modify the original system, the usual method is to add an auxiliary (damping) system to suppress the vibration of the original system. In this paper, we consider the optimal design of the damper for a linear damping system at a given excitation frequency, and discuss the numerical optimization results. System dynamics as shown in Figure 1, System 2 attached to the system 1, the entire system of dynamic equations can be expressed as:
