摘　　要：为了研究导弹发射时头部的压强环境,利用计算流体动力学软件Fluent对导弹发射时同心筒内流场进行数值仿真。建立前盖不加装凸台结构的计算模型,分析发射过程中导弹头部的压强环境,并把仿真结果与试验结果进行对比,仿真结果与试验结果吻合较好。然后建立前盖加装凸台结构的计算模型,并改变凸台结构的直径、高度和截面形状,研究这些参数对导弹头部压强环境的影响,发现前盖加装凸台结构能明显减弱导弹头部顶端的压强集中现象,通过优化凸台结构的直径、高度和截面形状,可以最大化减小导弹头部的压强峰值,为后续导弹头部压强环境的优化设计提供参考。In order to study the pressure environment of missile head during launching,the computational fluid dynamics software“Fluent”is used to simulate the flow field in the concentric cylinder during missile launching.The calculation model of the front cover without boss structure is established to analyze the pressure environment of the missile head during launching,and the simulation results are compared with the test results.The simulation results are in good agreement with the test results.Then,the calculation model of the front cover with boss structure is established,and the diameter,height,and section shape of the boss structure are changed.The influence of these parameters on the pressure environment of the missile head is studied.It is found that the front cover with boss structure can significantly reduce the pressure concentration at the top of the missile head.By optimizing the diameter,height and section shape of the boss structure,the peak pressure of the missile head can be minimized.This paper provides a reference for the optimization design of the pressure environment of the missile head.
