为深入研究水下航行体出筒过程运动姿态的响应过程，将多系统响应解耦为横向动力学与出筒导向2个课题，采用参数化建模的方法，对水下航行体的导向性能进行预报。采用优化设计的理念，对筒体支撑垫的位置、刚度进行优化设计，优化后筒体变形减小13%，变形曲线更加平滑，解决了导向性能与减震性能设计相互制约的问题，揭示了筒体变形的规律与内在机理，为水下航行体的姿态控制，导向性能等研究提供了研究方向。
In order to deeply study the response process of the motion attitude of the underwater vehicle during its ejection, the multi-system response is decoupled into two topics: lateral dynamics and ejection guidance, and the guidance performance of the underwater vehicle is predicted by the method of parametric modeling. The position and stiffness of the cylinder support pad are optimized with the concept of optimization design. After optimization, the deformation of the cylinder is reduced by 13%, and the deformation curve is smoother. The problem of mutual restriction between the design of guidance performance and shock absorption performance is solved, and the deformation law and internal mechanism of the cylinder are revealed. This provides a research direction for the attitude control and guidance performance of underwater vehicles.
