摘　　要：对大型结构件做模态试验是近年来振动界的热门话题之一。要对大型结构件做模态试验,一般都很费时费力,而且效果不一定好。在“微加速度测试系统”的基础上,将试验测试内容从大型结构件的“微加速度测试”扩展到大型结构件“模态试验”,在实际的模态试验中对测试设备、传感器、分析软件作必要的配置与完善,完成了对大型结构件的模态试验。可为需要对大型结构件做模态试验、响应试验提供参考。Recently the modal test of the large structure parts is one of the hot themes in the vibration domain. The modal test of the large structural parts is very troublesome and time-consuming. Based on the microacceleration test system, the modal test of the large structural parts is completed by expanding test content from micro-acceleration test to modal test, and configuring the test equipment, sensors and analytic software. And this method has application in the modal experiment of large structure, at the same time can be used for reference for those who conduct similar modal test.
