摘　　要：对传感器的优化布置进行了研究,从公式上推导了有效独立法和运动能量法,介绍了最小均方差的优化效果评价准则。然后以一平面桁架结构为算例,使用该两种优化方法进行传感器布置,并用评价准则对其布置效果进行比较。结果表明,使用有效独立法优于运动能量法,能更好的反映原结构特性。In this paper sensor placement methods have been studied.The formulas of effective independence method and kinetic energy method have been deduced by author.In addition,least mean square error criteria is introduced for estimating optimized results.Then,with the background of a steel truss,the above optimal approaches were used for sensor placement and their effects were evaluated according to least mean square error estimating criteria.Last,the results show that the effective independence method is better than the others methods,it can reflect structural character better.

关 键 词：传感器优化布置 有效独立法 运动能量法 钢桁架 评价准则
