摘　　要：为了探索高压柱塞泵滑靴副的摩擦磨损性能,需搭建一个滑靴副摩擦试验平台,针对该摩擦平台的运行要求,开发了一套电液控制系统,包括液压系统的设计、控制系统电路的设计以及软件的开发。为了实现该电液控制系统压力值的精确控制,引入了PID算法,通过仿真分析,得知此PID算法迭代2 603次后,该算法控制下的液压力逼近事先设定的压力值。开发结果表明,此电液控制系统能满足滑靴副摩擦试验平台的运行要求,从而为高压柱塞泵滑靴副摩擦磨损性能的研究提供了硬件支撑。In order to explore friction and wear properties of slipper pair in high pressure piston pump,a friction test platform of the slipper pair needs to be set up. Aiming at operation requirement of the friction test platform,an electro-hydraulic control system is developed,including design of hydraulic system,design of system control circuit and development of corresponding software. In order to implement accurate control of pressure value of the electro-hydraulic system,proportion integration and differential( PID) algorithm was introduced,and it was known that the pressure value controlled by the PID algorithm approached the set value very well after 2 603 times iteration calculation. The development results show that the electro-hydraulic control system can meet the operation demand of friction test platform of the slipper pair,thus,hardware support can be provided for studying on friction and wear properties of slipper pair in high pressure piston pump.
