飞机弹射起飞起落架动力学仿真分析

基于多体系统动力学的方法理论,应用ADAMS软件建立前起落架和主起落架的动力学仿真模型,并且以此为基础建立全机的动力学虚拟样机模型,对飞机弹射起飞过程进行仿真分析,并针对不同飞机起飞质量和弹射力,对比分析了其对起落架动力学响应及全机起飞性能的影响,结果表明:应用ADAMS对飞机起落架结构进行动力学仿真分析对起落架设计能提供必要的依据,减小飞机起飞质量以及增大弹射力,能够有效提高飞机弹射起飞性能。

The Dynamic Simulation on Landing Gear of Catapult Take-Off for Carrier-Based Aircraft

This thesis based on the theoretical method of multibody system dynamics, using the software ADAMS built the front landing gear subsystem and rear landing gear subsystem of carrier aircraft. And on this basis, aircraft subsystem is built. Simulation analysis was carried out on the aircraft catapult launch process; contrast the effect between different quality and ejection force. The results indicate that the application of ADAMS on dynamics simulation analysis for aircraft landing gear structure can provide necessary basis for landing gear design, the decrease of quality and the increase of ejection force can effectively improve the catapult launch performance.
