基于单向流固耦合技术潜射导弹出筒载荷研究

Launching Load Study of Submarine Missile Based on One-way Fluid-solid Coupling

为研究潜射导弹出筒过程中受载特性,基于单向流固耦合技术建立了导弹发射动力学数学模型,分析了两种艇速条件下导弹出筒过程中所受到的截面弯矩载荷。通过和缩比试验测试结果对比,表明仿真结果具有可信性。计算结果表明,导弹受载危险截面集中在弹身中部偏后的位置,且艇速对导弹受载和初始偏转角有重要影响。文中建模方法和计算结果对潜射导弹结构总体设计具有指导意义。

For the study of load characteristics of submarine launched missile,the mathematical model of missile launching dynamics was established based on one-way fluid-solid coupling technique,and the cross section bending load under the condition of two kinds of ship speed was analyzed.The comparison of the simulation results and the test results showed that the simulation results were reliable.The calculation results showed that the missile loading dangerous cross section concentrated in the middle of the body after the position,and the boat speed had important effect on missile loading and initial deflection angle.In this paper,the modeling method and the results of the calculation had guiding significance for the overall structure design of the submarine launched missle.
