摘　　要：为研究不同结构炮口制退器对两栖火炮炮口流场影响,采用CFD技术,结合动网格技术对弹丸进行处理,采用三维非定常可压缩流动的Euler方程和Realizable k-ε湍流方程对炮口流场进行数值模拟。通过数值仿真得到了炮口流场对车体不同部位的超压分布规律,结果表明,在冲击式炮口制退器下舱盖前端面上棱位置横向压力,与舱盖前端面下棱横向压力均比反冲击式的压力高。在炮口下方位置车体上表面横向位置,t=1.0 ms左右,在冲击式炮口制退器下的超压值比反冲击式高约为0.8 MPa。研究结果对两栖火炮炮口底盘相关设计、制退器结构选择提供了数据依据。In order to study the influence of different structures of muzzle brakes on the muzzle flow field of amphibious artillery,CFD technology was used to process the projectile combined with moving grid technology,and the three-dimensional unsteady compressible flow Euler equation and Realizable k-εturbulence equation were used to numerically simulate the muzzle flow field.The results show that the lateral pressure at the edge position of the front face of the hatch under the impact muzzle brake and the lateral pressure on the lower edge of the front face of the hatch are higher than the pressure of the reverse impact type.In the transverse position of the upper surface of the car body under the muzzle,t=1.0 ms,the overpressure value under the impact muzzle brake is about 0.8 MPa higher than that of the reverse shock type.The research results provide a data basis for the design of the muzzle chassis of the amphibious artillery and the selection of the brake structure.
