| 摘 要： | 为了解决确定数目条件下被动控制装置在相邻结构间的优化布置问题,利用改进遗传算法和控制系统H2性能指标对控制装置的位置进行了优化。分别采用Kelvin模型和Maxwell模型模拟黏弹性阻尼器和流体阻尼器,在双体单自由度结构间设立Kelvin型或Maxwell型被动控制单元的优化参数表达式,得到相邻高耸结构间控制单元的优化参数,通过相邻超高层结构算例验证了该控制设计方案的有效性和实用性。

| Abstract: | In order to obtain the optimal position of given number of passive dampers between two adjacent structures,an optimal arrangement was determined by using the H2 performance index and an improved genetic algorithm.The viscoelastic damper was represented by the Kelvin model and the fluid damper by the Maxwell model.The optimization parameter expressions respectively using the two model interconnecting two single degree of freedom(SDOF)systems were adopted and the optimal parameters of passive dampers intercon... |
