粒子群算法在网架结构应变传感器优化布置中的应用

Application of particle swarm optimization in optimal strain sensor arrangement of grid structure

通过ANSYS应用软件对网架结构进行模态分析和阵型求解,根据网架结构的振动特性选取合理的适应度函数。应用Matlab编辑粒子群算法的相关程序,得出网架结构传感器的最优布点。最后,通过一个应用算例验证该方法是可行而有效的。

The application software ANSYS was used for modal analysis and for mation solution, the reasonable fitness function was selected in accordance with the vi bration characteristics of grid structure. The related program of particle swarm optimi zation was edited by using Matlab and the optimal sensor distribution of grid structure was derived. Finally, the method is validated by an application example that the meth od is feasible and effective.
