摘　　要：针对传统双金属片形变检测方法误差大、效率低等问题,设计了一种基于激光位移传感器的形变测试系统。该系统基于"测位式"测试思想,利用非接触式激光位移传感器透过双层真空玻璃测量双金属片在不同温度下的形变量。系统以机械装置为基础,以计算机为上位机,并基于LabVIEW软件开发平台搭建控制系统,对激光位移传感器数据进行实时采集,并对采集的数据进行分析、处理、显示、输出,从而精确地测试出双金属片的形变量。试验结果表明:该系统性能稳定,各项控制功能均能实现。Aiming at problem of big error and low efficiency of traditional detection methods for bimetallic strip deformation, design a deformation test system based on laser displacement sensor. This system is based on concept of＂ location measuring type＂, making use of non-contact laser displacement Sensor, under different temperatures, to measure out amount of deformation of bimetallic strip through double-layer vacuum glass. The test system is based on mechanical device, and use computer as upper PC, establish control system based on LabVIEW. The system real-time acquires datas of laser displacement sensor, and then analyze, process, display, output, so as to accurately test deformation quantity of bimetallic strip. The test results show that the system performance is stable and all control functions can be realized.
