摘要 针对结构振动响应信号包含模态的测量可观性问题,利用有限元软件ANSYS对简支板结构进行了谐响应分析,然后根据各种输入情形下振动响应能量的分布对振动测试中传感器的布放位置及数量进行了设计,仿真分析与实验结果的一致性表明该方法是有效的。 In view of the problem on mode-observability in vibration test, a method for choosing the placement and number of sensors base on response power distributing has been worked out by the hands of harmonic response analyses. Experiment results indicated that this method was effective.
