In order to meet the mechanical performance requirement of aircraft throttle controller, find the weak link in the design, ensure the strength, stiffness and reliability of the product, the mechanical characteristics of the throttle controller were simulated and analyzed.The ANSYS software was used to analyze the stress and strain of the throttle drive controller under impact loading, and the modal analysis and random vibration analysis were carried out.The simulation results show that the design of the throttle controller is reasonable, the structure and the strength meet the requirements of the project.
