基于虚拟样机的起落架收放系统仿真

Aircraft Landing Gear Retraction and Extension System Simulation and Analysis Based on Virtual Prototype

通过建立某飞机起落架机构动力学模型和液压及控制系统模型,构建了完整的起落架收放系统的虚拟样机。基于虚拟样机,进行了起落架收放系统仿真分析,并与试验结果进行了对比。结果表明:仿真结果与试验结果基本一致,仿真模型可以用于起落架系统收放时间的模拟。

Landing gear mechanic dynamic model and hydraulic system model of a aircraft landing gear system were established, and the complete virtual prototype of the landing gear retraction and extension system was formed. Based on the virtual prototype, simulation and analysis of landing gear retraction and extension system were accomplished, the results of simulation were compared with that of laboratory test. It shows that simulation result is approximately comply with that of the laboratory test, the model can be used to simuate the landing gear vetraction or extersion.
