摘要

摘要: 针对飞机作动系统中效率较低,发热严重的情况,分析了电机泵阀并联协调控制作动系统中系统压力与系统效率的关系,提出了采用分级压力节能控制,即对电机泵组和阀控单位设定不同的最高压力,并根据作动系统的要求来确定系统采用的控制单元;用AMESim软件进行仿真验证和分析.结果显示,采用分级压力控制系统的发热量分别为单独高压阀控制和电机泵控发热量的27.9%和34.1%,明显地降低系统温升,减少了系统的发热损失,提高了系统的效率,从而增加了系统的寿命,保障了系统的安全性和可靠性.

Abstract: Based on the low efficiency and the significant heat loss of the aircraft actuating system, the relationship of pressure and efficiency was analyzed in the motor-pump-valve coordinated control actuation system. The method of the dual-stage pressure energy-saving control was proposed, that was, the different maximum pressures were set in the motor-pump and valve unit, and the control unit was determined by the requirement of the actuator system. The simulation and analysis were down by the AMESim software. The results indicate that the heat generated by the dual-stage pressure control system is only 27.9% and 34.1% of that generated by the high pressure valve control unit and the motor-pump separately. This method can obviously reduce the temperature increasing and heat losses of the system, the efficiency of the system can be improved, and consequently increase system life and maintain the security and reliability of the system.
