摘 要转动惯量作为一个重要的工程参数，如何准确地测量转动惯量在工程上具有重大意义
本文针对 ZME—1 综合力学实验台“三线摆"法测转动惯量测量实验，设计出一套能够较精确的测量物体转动惯量的实验辅助装置
该装置采纳非接触测量方式，可以方便、快捷、准确的猎取三线摆盘转动的周期信号
经在实验室检验该转动惯量测量装置，能准确稳定的采集到周期旋转信号

This thesis based on the trilinear pendulum method to measure the moment of inertia at the ZME—1 comprehensive mechanical bench
Designing a more accurate system to measure the moment of inertia, the system can display real—time swing cycle, automatically calculates the moment of inertia data
Designed non-contact measurement can be convenient， fast， accurate estimates of three-wire pendulum rotation cycle
The moment of inertia meas
