    摘要:

    炮口制退器在火炮的设计中起着至关重要的作用,它可以有效地降低火炮的后坐力。但负面效果是炮口冲击波引起炮手区域超压和超温。文章利用FLUENT软件进行炮口流场的数值模拟,对制退器性能影响因素进行仿真分析,得到规律;根据分析结果,得到改进后的制退器模型,并进行仿真对比。结果表明:加装侧孔外反射挡板和侧孔倾斜对制退器性能影响最大;加装吹孔能有效降低炮后超压和温度;改进后的制退器效率提升8.33%,炮后超压值平均降低44.099kPa,炮后温度值平均降低358.284K,由此证明改进后的制退器具有更高的制退效率以及较低的炮后超压值和温度值。分析过程中所用到的方法和得出的结论对制退器的研究具有一定的指导意义。

    Abstract:

    Muzzle brake plays a crucial role in gun design, it can effectively reduce the recoil of the gun. But the negative effect is that the muzzle shock wave causes overpressure and overtemperature in the gunner''s area. In this paper, the numerical simulation of muzzle flow field was carried out by FLUENT software, and the influencing factors of brake performance were simulated and analyzed, and the rules were obtained. According to the analysis results, the improved brake model was obtained, and the simulation was compared. The results showed that the performance of the brake was most affected by the side hole external reflection baffle and the side hole inclination. The overpressure and temperature behind the muzzle were reduced effectively by installing the blow hole. The efficiency of the improved brake was increased by 8.33%, the overpressure behind the muzzle was decreased by 44.099kPa on average, and the temperature behind the muzzle was decreased by 358.284K on average. It was proved that the improved brake has higher efficiency and lower overpressure value and temperature value behind the muzzle. The method used in the analysis process and the conclusion obtained have certain guiding significance for the research of brake.
