针对水下航行器的舱门在开启过程中航行器外形会发生变化的情况，对航行器舱门开启过程的流体特性进行仿真分析。根据舱门开启过程的流体特性，将得到的流体系数作为航行器动力学方程参数的变化曲线，对舱门开启过程的运动进行了仿真，并给出详细的计算过程。仿真结果表明：该舱门开启过程设计合理，随着舱门的开启，虽然航行器的速度和攻角有所下降，但各物理量的变化幅度仍然在常规范围内，该方法为水下航行器存在外形变化时的运动仿真提供了思路。

Aiming at the shape changes of the underwater vehicle at the cabin door opening, simulate hydrodynamics features of cabin door opening process. According to hydrodynamics feature of cabin door opening process, take hydrodynamics index as variation curve of vehicle dynamics equation index, simulate cabin door opening movement, then give the calculation process in detail. The simulation results show that the cabin door opening design is reasonable. When door is opening, the speed and attack angle decrease, but the changing amplitude of physical quantity is normally. The method will give reference for movement simulation when the underwater vehicle is changing in shape at movement.
