摘　　要：通过建立飞机着陆弹性机体等效多质量模型,导出了着陆系统的微分方程。基于ADAMS/Aircraft软件建立了含弹性机体的全机着陆虚通拟样机,仿真出飞机着陆时的动态响应。着陆仿真分析结果与初始设计值的一致性较好,误差在5%以内,为大飞机起落架设计过程中考虑机体弹性的影响提供了有益的参考。The differential equations of airplane system with flexible wings and fuselage are deduced by the establishing of equivalent model. The virtual prototype of the plane with flexible fuselage is built in ADAMS/Aircraft, a series of simulations of dynamics responses are anylazed. Simulations anylasis results show the consistency between initial design data and simulation data, since the errors are all under 5%. This method provides helpful reference for the design of civil airplane with flexible fuselage.
