摘　　要：在航空母舰上引入降落区的概念,考虑航空母舰的运动模型,建立了舰载机在该降落区上降落时的简化分析模型;推导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,采用数值分析方法解出飞机垂直撞击舰面降落区这一过程的动态响应,给出机身载荷-时间历程曲线和舰面垂支反力-时间历程曲线等。与原模型分析结果相比,机身受载和舰面垂直反力峰值减小分别37.3%和37.2%,有效地减小了舰载机着舰的冲击载荷。The conception of landing area is introduced to the aircraft carrier, and a simplified model of the conventional oleo-pneumatic landing gear during the process of landing impact on the landing area is established. The mathematic model is also derived. The dynamic response of the landing gear landing vertically is calculated via Runge-Kutta procedure. Simulation results for both the original model and the new model are presented to illustrate the effectiveness of the new model. The result shows that the maximum of the impact loads on airframe and the maximal ground reaction force are reduced 37.3% and 37.2% respectively.
