光电位移跟踪器系统测速标定方法的分析

Analysis of Calibration Method for Velocity Measurement with the Electro-Optical Displacement Follower.

本文介绍一种采用光电位移跟踪器与微机数据采集处理系统相结合的手段进行自动机位移曲线和速度曲线测试的新方法.通过对旧的速度标定方法不足之处的分析,提出了一种新的速度标定方法——积分标定法,使速度测试精度与效率明显提高.

This paper presents the measurement of the dis- placement versus time and the velocity versus time of the automatic mechanism by means of combining the electro-optical displacement follower with microcomputer data processing system.Based on the analysis of general method calibrating velocity curve,a better method ——the integral calibrating method is introduced,which improves greatly both accuracy and efficiency of measuring the velocity curve.
