摘　　要：采用NX Simcenter3D软件建立舱门刚柔耦合动力学模型,得到各构件的运动数据及路径,并与实物模型对比调试,以保证该设计方案的可行性及安全性能。解得每一运动副各时刻所传递的力与转矩,确保舱门开启时所用手柄力矩大小及移动轨迹满足舱门使用需求。对舱门结构关键部位建立柔性体,创建动态耦合模型,对薄弱部位进行仿真分析、计算刚度与强度校核,为舱门机构的改进设计提供依据。The rigid and flexible coupling dynamics model of the cabin door established via NX Simcenter3D software was used to obtain the motion data and paths of each member,and the comparison and debugging with the real model were conducted to ensure the feasible and safe performance of the design scheme of the cabin door mechanism of this type of aircraft.The force and torque transmitted by each motion pair at each moment were solved to ensure that the handle torque applied upon door opening and its movement trajectory met the use requirements of the hatch door.The flexible body of the key parts of the cabin door structure were established,the dynamic coupling model was created,the weak parts were simulated and analyzed,the stiffness and strength were calculated and checked,which provided the basis for the improved design of the cabin door mechanism.
