基于工控机的曲轴不平衡信号检测系统

A MEASUREMENT SYSTEM BASED ON INDUSTRIAL PC FOR UNBALANCE SIGNALS OF CRANKSHAFTS

介绍了一种以工业控制计算机为核心的曲轴不平衡信号检测系统。该系统与德国ＨＬ－２０ＫＶＡ曲轴动平衡机配套使用，可以满意的精度检测出曲轴不平衡量的大小及其角度位置，不平衡量（５０ｇ·ｃｍ－３００ｇ·ｃｍ范围内）重复测量误差≤１５ｇ·ｃｍ。本系统的研制具有投资少、开发周期短以及便于在线维修等特点。

A measurement system for unbalance signals of crankshafts,which is mainly based on an industrial control computer,is introduced.With the system combined with a HL-20KVA dynamic balance machine made in Germany,the amplitude and the angular position of crankshaft unbalances can accurately be measured,and the repeat measarement error of unbalance within 50 g·cm～300 g·cm is less than 15 g·cm.In addition to easily modifing for design on line,goals of low cost and short time for research and development of the system are reached.
