摘要基于重叠网格技术与6自由度算法对某一高速旋转射弹波浪中入水过程进行了数值模拟研究，分析了波峰、波节1、波谷、波节2等波面不同位置入水弹体空泡形态、弹道特征及流体动力载荷特性变化规律。研究结果表明：四种工况弹体均经历撞水、空泡形成、超空泡航行与沾湿，其中波节2弹体尾部最先与空泡壁面碰撞产生沾湿，波节1发生尾部沾湿最晚；四种工况弹体质心运动轨迹均产生了不同程度的偏转，仿真结束时侧向位移量、速度变化量由大到小工况依次为波节2、波峰、波谷和波节1；四种工况入水初期弹体在空泡中航行受到的力和力矩系数量级均较小，入水后期弹体表面大面积沾湿不同工况下的力和力矩系数有较大差别；四种工况弹体名义入水角相同均为25°，由于波面的存在弹体实际有效入水角发生了变化，它们由小到大工况依次为波节2、波峰、波谷和波节1，其值依次为10.3094°、25.0032°、25.0098°和39.6620°。

Abstract：Based on the overlapping grid technique and 6-DOF algorithm, the numerical simulation of the water entry process of a high-speed pinning projectile in waves is carried out. The cavitation shape, trajectory characteristics and hydrodynamic load characteristics of the projectile at different positions of wave surface, such as wave crest, wave node 1, wave trough and wave node 2, are analyzed. The results show that the projectile body experiences water impact, cavitation formation, supercavitating and wetting under four cases, among which the tail of wave node 2 collides with the cavitation first, and the tail of wave node 1 collides with the cavitation last. At the end of the simulation, the lateral displacement and velocity change from large to small are wave node 2, wave crest, wave trough and wave node 1. In the initial stage of the four cases, the force and moment coefficients magnitude of the projectile sailing in the cavity are small. In the later stage of water entry, the surface of the projectile is wet in a large area. The force and moment coefficients under different cases are quite different. The nominal entry-water angle is 25 degree and the same under the four cases, but due to the existence of wave surface, the actual entry-water angle of the projectile change. The effective entry-water angle of the projectile from small to large are wave node 2, wave crest, wave trough and wave node 1, and the values are 10.3094 degree, 25.0032 degree, 25.0098 degree and 39.6620 degree respectively.

Key words： high-speed spinning projectile wave entry overlapping grid wave-generation method of defining inlet boundary conditions;
