Modeling and Simulation on Dynamics of Vertical Launching for Submarine-borne Missile

分析了潜艇带速水下垂直发射导弹过程中导弹所受到的流体动力特性、弹体与弹性密封环的相互作用,建立了水下动机座垂直发射导弹的动力学模型,提出了导弹仿真耦合算法,给出了弹道仿真算例。为导弹垂直发射弹道控制、发射安全性评估、导弹与发射系统设计提供理论基础与研究手段。

A computer model was developed to analyze the effect of the underwater fluid dynamic parameters on the vertical launch from the kinetic platform. This model is a time-dependent, three freedom, motion equations which is considered with the fluid hydrodynamics characteristics and stress feature of the spring seal ring＇s deformation and coupling between missile and ring. Coupled algorithm was advanced and simulated. The research is helpful for the design and tests of missile vertical launching system, the control of trajectory, launch safety assessment and missile launching system design.
