考虑水下航行体的弹性特性,建立航行体与发射筒之间接触、摩擦作用的刚柔耦合模型,发展了多约束航行体水下垂直发射动力学仿真分析方法。给出算例,获得了筒内弹道、水中弹道、航行体姿态和内部载荷等参数的变化规律。分析表明,计算结果能够反映航行体水下垂直发射过程的特点,计算方法合理可行。
攷慮水下航行體的彈性特性,建立航行體與髮射筒之間接觸、摩抆作用的剛柔耦閤模型,髮展瞭多約束航行體水下垂直髮射動力學倣真分析方法。給齣算例,穫得瞭筒內彈道、水中彈道、航行體姿態和內部載荷等參數的變化規律。分析錶明,計算結果能夠反映航行體水下垂直髮射過程的特點,計算方法閤理可行。

A rigid-flexible coupled model considering contact and friction between underwater vehicle and launching tube was proposed, and dynamic simulation method for vertical sub-launching process of multiple constraints elastic body was established. The results of calculation example are introduced, which contain the varying rules of parameters such as trajectory in the tube, trajectory in water, vehicle attitude and inner load. The analysis indicates that the calculation results can catch the characteristic of underwater vehicle’s vertical sub-launching process, and the method is reasonable and feasible.
