建立了民用飞机起落架缓冲系统的数学模型,并根据建立的模型在ADAMS/Aircraft仿真模块中建立了全机虚拟样机模型,然后在两种不同跑道上进行了滑跑仿真,分析了具有单腔和双腔缓冲器的飞机在两种跑道上滑跑的动态响应。结果表明,双腔缓冲器的飞机在粗糙道面上滑跑时产生的过载和峰值载荷较小,而且振动也较单腔缓冲器飞机平缓,并且具有良好的越过连续小丘的能力。双腔缓冲器能够更好地提高机组人员及乘客的舒适性,并在一定程度上减小机体疲劳载荷延长飞机的使用寿命。
The mathematic model of the civil aircraft landing gear cushioning system is established. According to the established model, a full-machine virtual prototype model is established in the ADAMS / Aircraft simulation module. Then the slip simulation is performed on two different runways. And the dynamic response of the double-bumper aircraft running on both runways. The results show that the double-chamber bumper aircraft produces less overload and peak loads when run on a rough surface, and vibrates more smoothly than single-chamber bumper aircraft and has good ability to cross continuous humps. Double-chamber bumpers can better enhance the crew and passengers comfort, and to a certain extent, reduce the body fatigue load to extend the life of the aircraft.
