摘　　要：叶片是汽轮机的重要工作部件,为了研究其在不同激振力下的振动特性,针对实验室新搭建的汽轮机叶片动态特性试验台,基于LabVIEW开发了用于测量和分析汽轮机叶片振动测量系统。该测量系统具有叶片振动信号采集、信号处理、信号分析、数据保存和数据回放功能。在本文中,将介绍实验台组成、测量系统硬件选型、系统开发流程和各功能模块的编程。最后,采用该系统做了叶片静频和动频的测量实验,结合理论分析和实验结果表明,该测量系统是可靠的。The blades are the important components of the turbine unit. In this paper, the measurement system of the turbine blades＇ Dynamic characteristic will be developed to research the vibration characteristic with the different exciting Force. The signal acquisition, signal processing, signal analysis, signal preservation and data recalling will be developed in this system. The composing of test bench, hardware of measurement system, the development flow and function modules of system will be introduced in this paper. At last, the experiment of natural frequency and Dynamic frequency proved that the system is trustiness with the theory analysis.
