中文摘要:

一个连续可变优化方法和一个拓扑的优化方法为颤动控制被建议压电借助于活跃工具条的最佳的放置捆绑结构。在这个优化模型,一个零一个的分离变量被定义以便解决压电的活跃酒吧的最佳的放置。同时,反馈获得也作为连续设计变量被优化。一个二阶段的过程被建议解决优化问题。顺序的线性编程算法被用来解决优化问题,敏感分析被执行让目的和限制函数做线性近似。根据结构的短暂动态回答的 Newmark 时间集成,一个新敏感分析方法为颤动控制问题在这篇论文被开发压电关于设计变量的各种各样的类型捆绑结构。数字例子在纸被给表明方法的有效性。

英文摘要:

A continuous variable optimization method and a topological optimization method are proposed for the vibration control of piezoelectric truss structures by means of the optimal placements of active bars. In this optimization model, a zero-one discrete variable is defined in order to solve the optimal placement of piezoelectric active bars. At the same time, the feedback gains are also optimized as continuous design variables. A two-phase procedure is proposed to solve the optimization problem. The sequential linear programming algorithm is used to solve optimization problem and the sensitivity analysis is carried out for objective and constraint functions to make linear approximations. On the basis of the Newmark time integration of structural transient dynamic responses, a new sensitivity analysis method is developed in this paper for the vibration control problem of piezoelectric truss structures with respect to various kinds of design variables. Numerical examples are given in the paper to demonstrate the effectiveness of the methods.
