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.
