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.
Key words: structure test; loading actuator; electro-hydraulic; AMESim simulation
