转向器滚珠丝杆导程误差动态检测仪的研究

介绍了一种采用微型计算机的新型滚的丝杆动态检测仪的工作原理。系统结构，计算机接口电路，仪器误差分析及实验结果，其主要特征是采用同步位移比较原理进行绝对测量，采用误差修正技术修正仪器误差，以达到较仪器自身精度为高的检测精度。

The Development of Dynamic Measuring Instrument for Checking Lead Errors of Ball Screws of Steering Mechanism

A new type of measuring instrument which is used to measure lead errors of ballscrews has been developed. The principle of the inStrument,the system strucrure,the computer inter-face. The analyses of the instrument error and the experimental results are presented, The principleof comparing synchronous displacement is used to achieve absolute measurement. The errors correc-tion technique is adopted to correct the errors of the instrument so that the high measuring accuracycan be botained.
