The method of the optimum disposal of sensors on the basis of structural dynamics in mode strain energy and instance

针对平面桁架结构和空间钢网架结构的传感器优化布置方案进行了概述和讨论,应用动力模态应变能理论模拟优化一平面钢桁架和一实际空间钢桁架结构的传感器布置,对算例进行了分析计算。应用Matlab语言开发编程,从而快速有效的实现传感器的优化布置。并对计算结果加以分析,得出一些有意义的结论。

The article provides the specific discussion and summary of the optimum disposal of sensors aiming at the plane truss and space steel grid.It takes the advantage of theory in mode strain energy to realize the accurate disposal of sensors in an artificial plane truss and a space steel truss of real project.Also,we exploit beneficial programs by Matlab so as to address the similar problems fast and efficiently.Finally,we have a close research with the outcome,from which we are able to deduce some instructive conclusions.
