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.关键词：转动惯量，三线摆，实验辅助装置，非接触式测量ABSTRACTThe moment of inertia as an important engineering parameters， how to measure the moment of inertia accurately has a magnificent significance in the project.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 measure equipment has been tested in the laboratory that can collect the periodic turn signal accurately and stably。Key words ： Moment of Inertia, Trilinear Pendulum, Measurement System, Assistive Devices, Non-contact measurement目 录第 1 章 引 言....................................................11。1 讨论意义.................................................11.2 国内外讨论现状............................................11。3 主要讨论内容.............................................2第 2 章 转动惯量的运用讨论与测量.................................42。1 转动惯量的物理意义及其运用...............................42.2 现有的转动惯量测算方法.....................................62。3 各种测算方法分析.........................................10第 3 章 测试装置设计............................................123.1 测试装置技术要求.....................................
