主要研究了在吊车正常工作工况下,采用东华测试DH5920型动态信号测试分析系统对吊车梁进行挠度测量的原理及方法,利用动力测试系统的测量方法与传统的方法相比,表明动力测试系统不需要在测量时停止现场作业,可以通过传感器,在正常工作的工况下进行方便的测量,其测量结果也能够较好地反映出实际工作状态下吊车梁各个测点位置的挠度大小。

This paper mainly studies the principles and methods of applying Donghua DH5920 dynamic signal testing analysis system to survey the crane deflection under the normal working condition.Comparing the survey method of dynamic testing system to traditional method,it finds out that dynamic testing system can carry out convenient measurement under normal working condition with the transducer without stopping field operation.Furthermore,the surveying result can better reflect the deflection of each surveying point of crane beam in actual working condition.
