两栖战车海上行进间发射动力学研究

Research on the Launching Dynamics of Amphibious Combat Vehicle Launching at Sea

针对两栖车辆在海上行进时,所携带的导弹受力与发射姿态情况复杂的问题,对该两栖战车和海浪模型进行合理简化和假设,建立了两栖战车在随机海浪激励下的动力学方程。利用动力学仿真软件得到了大量导弹发射初始扰动数据,并采用统计学方法和正交实验思想对数据进行分析。分析结果表明,两栖战车在四级海况迎浪行进的情况下,搭载的导弹发射初始扰动具有很好的正态分布规律,且导弹发射的高低射角比水平射角更能影响导弹发射的稳定性。

Aiming at the complex problem of the force and launch attitude to the missile carried by the amphibious vehicle when it is traveling through the sea, the amphibious vehicle and the wave model are reasonably simplified and assumed, and the dynamic equation of the amphibious vehicle under the excitation of random waves is established. A large number of initial disturbance data of missile launching are obtained by using dynamic simulation software, and the data are analyzed by using statistical methods and orthogonal experimental ideas. The analysis results show that the initial disturbance of missile launch carried on the amphibious vehicle has a good normal distribution law when the amphibious vehicle is traveling against the waves of the fourth level sea state, and the high and low launch angles of missile launch can affect the stability of missile launch more than the horizontal launch angles.
