摘　　要：根据电液比例阀性能测试规范,开发了用于电液比例阀性能测试的计算机辅助测试(CAT)系统。利用虚拟仪器技术,设计了CAT系统软件,实现了测试系统所要求的信号发生器、系统参数调整与控制、信号采集与处理、数据分析计算等功能。使用结果表明,测试系统运行稳定、结果可靠、人机界面友好,提高了比例阀特性测试精度和测试效率。According to the test criterion of electro-hydraulic proportional valves, the computer aided test （CAT） system used to test the characteristic of electro-hydraulic proportional valves is developed. The CAT system software is programmed based on the technology of virtual instruments. These indispensable functions are implemented to CAT system, such as signal generator, system parameters regulating and controlling, signal acquire and process, test data process, etc. The practical result shows that test system is stable, reliable and better HMI. The test precision and efficiency is obviously improved.
