电动缸性能参数测试系统设计

针对现有的电动缸测试系统和测试方法不能满足电动缸产品出厂参数快速测量的问题,研发了一套以PC机作为上位机,雷赛DMC5480运动控制卡作为核心控制器,高精度磁栅尺为检测装置的电动缸性能参数测试系统。根据测试需求设计了开放式电动缸测试系统、测试方法和功能测试模块;结合数据测量装置,基于VB和API函数研发了开放式电动缸自动测试系统软件平台,包括电动缸的位置精度、回程误差、重复定位精度、误差分析与补偿及跟随误差测试等功能模块。该测试系统成功应用于某公司电动缸出厂参数快速测量。

Design of a parameter measurement system for electric cylinder

In order to solve the problem of current electric cylinder test system and test method can’t meet the requirements of electric cylinder performance test,a parameter measurement system is designed in the paper and it contains industrial computer as upper machine,and Leisai DMC5480 movement control card as center controller,and high precision magnetic grid ruler as detection device.Firstly,an open automatic test system and test method for electric cylinder and function test module are designed for the system.Then, combining with data detection device,by the VB and API function library,the paper designs open hardware structure and software platform for the system,which includes location accuracy,return error,repeat positioning accuracy,error analysis and compensation,and error analysis and compensation as well.The system has been successfully applied to the electric cylinder parameter measurement of a company.
