为研究两栖车行进间发射的导弹出筒姿态分布规律及影响因素,对某型两栖车进行受力分析,建立其在随机海浪作用下的行进间发射动力学模型。对两栖车行进间发射过程进行多次动力学仿真,利用统计学方法对仿真结果进行分析,进一步得到统计学结果。结果表明:在随机海浪激励下,导弹出筒姿态分布规律符合正态分布;平均风速以及航行速度越小,导弹出筒姿态越好;两栖车尾斜浪航行时,其发射安全性较高。

To study the distribution law and influence factors of the missile’s outlet attitude, the force analysis of a certain type of amphibious vehicle is carried out, and the dynamic model of the amphibious vehicle launching on the move under the excitation of random waves is established. The launch process of amphibious vehicle is simulated for many times, and the simulation results are analyzed by statistical method, and the statistical results are obtained. The results show that: under the excitation of random waves, the missile’s attitude distribution law conforms to normal distribution; the smaller the average wind speed and the navigation speed, the better the missile’s attitude; when the amphibious vehicle’s tail sails in oblique waves, its launching safety is higher.
