本文闸述了以叶片振动疲劳试验系统为例,使用微机系统、位移传感器、模拟量输入和输出装置等组成的检测与负反馈闭环控制系统。该系统采用高级语言和汇编语言子程序嵌套方式,实现了对叶片疲劳试验系统的自动检测与控制,也兼容于燃滑油管系统的疲劳实验。 This paper describes a vane vibration fatigue test system, for example, the use of computer systems, displacement sensors, analog input and output devices and other components of the detection and feedback closed-loop control system. The system uses high-level language and assembly language subroutine nesting method to achieve automatic detection and control of blade fatigue test system is also compatible with the fatigue test of the fuel pipe system.
