电动负载模拟器结构轴设计

Electric load simulator is one of the important equipment of all kinds of vehicles in the design stage of semi physical simulation on the ground, used to simulate the aerodynamic loading in the rudder surface during the flight. In view of the different load on the rudder in the air, design a composite force loading system which can load the torque and bending moment at the same time and the overall scheme are be given. This paper introduces the system structure and mechanical structure of the electric load simulator and describes its working principle. Designing and checking the motor shaft, spring beam and tooling shaft of the electric load simulator by using the theory and method of the mechanical optimization design, making the system achieve the optimal design on the premise of meeting the practical requirements. Then the structure of shaft is simulated and analyzed in the loading mode of static and dynamic.
