| 摘 要： | 本文建立了主被动一体化振动控制复合结构的一般运动方程，在此基础上，建立了主动与被动构件优化配置问题的模型，推导了闭环控制下结构模态阻尼比的求解公式，并以此为目标函数，实现了用模拟退火搜索算法求解主动、被动构件位置优化问题的过程。通过一个空间桁架算例，实现了多个粘弹性阻尼构件与层积式压电推构件杆的位置优化配置，分析讨论了被动阻尼控制对主动构件位置优化的影响。

| Abstract: | A system-governing equation of the complex structure integrated Passive and Active Vibration Control is founded in this paper. Based on it, a model of optimal placements of actuators and passive bars is properred and a formulas of mode damping ratio of complex structure under closed controlled has been gotten. It is succeeded to process the optimization problem of actuors and passive bars using simula ted annealing heuristic. One example of space-truss is used to demonstrate the methods, and analysis the interact between the disposition of passive bars and actuator. |
