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.
Aiming at the low efficiency and serious heating condition of the airplane operating system, the relationship between the system pressure and the system efficiency in the parallel coordinated control actuation system of the electric motor pump was analyzed, and the energy saving control with classification pressure was put forward, that is, The control unit sets different maximum pressure and determines the control unit to be used in the system according to the requirements of the actuation system.The simulation and analysis with AMESim software show that the calorific values of the pressure control system with separate pressure are separately controlled by a single high pressure valve And motor pump control 27.9% and 34.1% of the calorific value, significantly reducing system temperature rise, reducing system heat loss and improve the system efficiency, thereby increasing the life of the system to protect the safety and reliability of the system.
