摘要
研究了节流调速回路的计算机辅助测试原理，制定了系统试验参数的测试方案，设计了计算机辅助测试系统的硬件及软件，实现了压力的自动测量及连续控制速度的自动测量、曲线绘制等功能，软件全部采用菜单提示，具有良好的人机界面，使用方便，该系统在QCS008液压实验台上进行了调试试验，结果表明，系统的运行稳定可靠。
The paper approaches the principles in computer aided test(CAT) of the throttling speed - regulating loop. It offers the test scheme of the experimental parameters and the design of software and hardware of the test system,which enable the pressure and continuously controlled speed to be measured automatically. The system also has the capacity of drawing curves and a good interface. Tested on QCS008 hydraulical test table, it proves to be stable and reliable inoperation.
