摘要

以含弹性适配器导弹运载器的跨介质弹射分离问题为对象

基于分数容积障碍法

采用流体体积多相流理论和RNG

k-ε

湍流模式建立导弹运载器水面分离多物理场耦合模型。以圆柱体入水为仿真算例进行数值模拟

计算值与实验结果吻合良好

验证了数值模型的精度和有效性。分别对导弹在波谷、波峰环境下的弹射出水

以及在不同初始俯仰角和出水初速度下的弹射分离过程进行数值模拟

得出初始俯仰角、出水速度、出水位置对运载器式导弹水面分离的影响。综合考虑波峰、波谷位置出水筒-弹分离时刻导弹的俯仰角并以波谷位置出水筒-弹分离时刻导弹俯仰角达到0°为准则

得到最佳初始俯仰角为3.24°。仿真方法和结果对工程应用具有重要参考价值。

Abstract

In order to solve the problem of transmedia ejection separation of missile carrier with elastic adapter

based on the fractional areas-volume obstacle representation (FAVOUR) method

a multi-physical field coupling model for missile separation from the carrier near the free surface is established by using the RNG

k-ε

turbulence model and VOF function. The numerical simulation of the water entry process of the cylinder is carried out

and the calculated results are consistent with the experimental data

which verifies the rationality of the numerical model. The ejection and separation processes of the missile in trough and crest environments and at different initial pitch angles and initial velocities of water exit are numerically simulated

and the effects of initial pitch angle

water exit velocity and position above the water surface on the submarine-launched missile separated from the carrier are obtained. Considering the pitch angle of the missile at the moment of separation from the launch tube at the wave crest and trough positions

the optimal initial pitch angle is 3.24° based on the criterion that the pitch angle of the missile reaches 0° at

the separation time at the wave trough position. The simulation method and results are of referential significance for engineering applications.

Therefore, it is difficult to establish the accurate water-exit dynamic model. In the paper, according to the characteristics of the water-exit motion, based on the traditional method of added mass, considering the added mass changing rate, the water-exit dynamic model is established. And with help of the CFX fluid simulation software, a new calculation method of the added mass that is suit for submarine-launched missile is proposed, which can effectively solve the problem of fluid solid coupling in modeling process. Then by the new calculation method, the change law of the added mass in water-exit process of the missile is obtained. In simulated analysis, for the water-exit process of the missile, by comparing the results of the numerical simulation and the calculation of theoretical model, the effectiveness of the new added mass calculation method and the accuracy of the water-exit dynamic model that considers the added mass changing rate are verified.
