摘要
考虑航空母舰运动对于舰载机起落架着舰的影响,建立了舰载机起落架着舰时的动力学分析简化模型。给出了基于该分析模型的运动微分方程及相关参数的表达式,并采用龙格库塔算法对舰载机起落架垂直撞击舰面这一过程的动态响应进行了数值仿真,给出了机身受载时间历程曲线等,通过着陆与着舰仿真结果的对比,阐释了航空母舰运动对舰载机起落架着舰的影响和航空母舰的运动参数对舰载机起落架着舰冲击力的影响。
The effect of carrier＇s motion on the process of landing impact was taken into account, and a simplified model of the conventional oleo-pneumatic landing gear during the process of landing impact on the carrier was established. The mathematical model was also derived. The dynamic response of the landing gear landing vertically was calculated via Runge-Kutta procedure. Simulation results for both landing on the ground and landing on the carrier are presented to illustrate the effect of carrier＇s motion on the process of landing impact. Furthermore, studies are also made to determine the effect of variations in some parameters of carrier＇s motion.
