摘　　要：驻退机是舰炮反后坐装置的重要组成部分。驻退机传统的设计计算方法复杂,误差较大,所能收集的数据有限,无法得到整体流场的情况。某舰炮在长连发射击试验时,出现复进时间长的故障。对该问题传统设计方法计算与射击试验结果不符。本文采用计算流体力学方法对驻退机流场重新进行分析,通过计算机模拟仿真,研究驻退机内部流场的变化规律,利用流体力学相关理论解决实际工程问题,为解决复进时间长问题提供参考。Recoil brake is an important part of a naval gun recoil mechanism,The traditional design of recoil brake has large errors and could get very limited data.The whole flow field can not be obtained.The problem of long recovery time for a naval gun will appear in long-term launch shock test.With regard to this problem,the calculation of traditional design method is inconsistent with the result of firing test.In this paper,the CFD method is used to re-analysis the flow field of the recoil brake.Through computer simulation and analysis,the variation law of internal flow field in recoil brake is studied,and the practical engineering problem are solved by using the hydrodynamics theory.It also provides a reference for solving this problem of long recovery time.
