本文介绍整机测试中常用的几种位移测量方法、特点及其应用,以求达到实用的目的。工程机械整机进行测试时,往往需要在车辆运行过程中测量构件的位移(包括线位移和角位移)。而且,常常需要测量各构件位移量之间以及与时间、载荷等参数之间的相互关 This article introduces several commonly used displacement measurement methods, features and their applications in machine testing, in order to achieve practical purposes. Construction machinery testing machine, often need to measure the movement of vehicles during the component displacement (including the line displacement and angular displacement). Furthermore, it is often necessary to measure the correlation between the displacements of various components and with parameters such as time, load, etc.
