摘要: 针对飞机结构试验尤其是静力试验中加载速度低、系统流量低的特点,设计了一种新型的基于阀控的飞机结构加载试验用的电液一体化作动器,阐述了其系统组成和工作原理,分析了阀控系统的效率问题,提出降低油源压力设计值来提高系统效率的方案,并通过AMESim高级建模仿真平台,对该电液一体化作动器系统进行建模仿真,验证了降低油源压力设计值方案对提高系统效率的有效性.其仿真结果表明所设计的电液一体化作动器能够满足设计要求,在飞机结构加载试验中具有很好的应用前景.

Abstract: Based on the characteristics of low speed and low system flow in plane structure test especially in the static loading test, a new type of valve-control electro-hydraulic actuator for aircraft structure loading test was designed. The system components and working principle was described, and the efficiency of valve-control system was analyzed. A scheme of reducing the oil source pressure setting was proposed in order to improve the system efficiency, while modeling and simulation work of the electro-hydraulic actuator system was completed through the AMESim platform, and the effectiveness of proposed scheme in improving the system efficiency was proved. The simulation results demonstrate that the designed electro-hydraulic actuator can totally meet the expected design requirements, and can be widely used in aircraft structural loading test system.
