摘　　要：采用LabVIEW与MATLAB函数结合的方法,开发了冶金高频响高精度伺服液压缸性能测试系统。根据生产冶金高频响高精度伺服液压缸对其动静态性能指标要求,该测试系统功能模块包含最低起动压力测试模块、带载动摩擦力测试模块、阶跃响应测试模块、频率响应测试模块、偏摆测试模块,各项测试结果通过研华数据采集卡PCI-1742U、PCI-1723与SSI-RS485电流变送器转换采集MST位移传感器信号与AB相脉冲传感器信号;该测试系统能够对测试的数据进行实时跟踪显示、存储或查询;此外,该系统还具有数据导出、打印实验报告等辅助功能。实验证明,该测试系统具有较高的实时性与可操作性,填补了其他系统所空缺的针对于大直径冶金高频响高精度伺服液压缸的偏摆测试模块,同时该测试系统具有更高的稳定性,解决了技术人员对原有测试系统操作复杂的难题,实现“傻瓜式”操作,更加智能化、可视化、及时化。This article presents the development of a performance testing system for metallurgical rolling servo hydraulic cylinders,which uses a combination of LabVIEW and MATLAB functions.The testing system includes functional modules for evaluating the dynamic and static performance requirements of the cylinders,such as testing the minimum starting pressure,loaded dynamic friction force,step response,frequency response,and swing testing.To collect the test results,the system uses Advantech data acquisition cards,including PCI-1742U,PCI-1723,and SSI-RS485 current transmitters,to gather signals from MST displacement sensors and AB phase pulse sensors.The system is capable of real-time tracking,display,storage,and query of test data,as well as data export and report printing.Experimental results demonstrate that the system exhibits high real-time performance and operability,and fills the gap left by other systems in terms of swing testing for large-diameter metallurgical rolling servo hydraulic cylinders.Additionally,the testing system offers greater stability and solves the problem of complex operation for technical personnel who used the previous testing system.The system achieves “foolproof” operation and greater intelligence,visualization,and timeliness.
