为减小炮口制退器质量，提高射击精度和密集度，对钛合金在炮口制退器上的应用进行研究。以计算流体动力学以及有限元理论为基础，综合应用计算流体力学数值仿真技术和有限元分析方法，完成了从炮口制退器炮口流场三维数值模拟到有限元分析的全过程，得出了TC4钛合金和炮钢材料下的炮口制退器应力分布和变形结果。结果表明：在满足使用条件的情况下，T C 4材料的使用能减轻炮口制退器的质量，从而可减小其它部件的设计难度。%In order to reduce the mass of muzzle brake and improve firing accuracy and density, the application of titanium alloy in muzzle brake was researched. Based on the theory of computational fluid dynamics and the finite element theory and the application of computational fluid dynamics (CFD) numerical simulation and finite element analysis method, the entire process of the three-dimensional numerical simulation flow field of the muzzle brake and finite element analysis was accomplished. Stress distribution and deformation results of TC4 and gun-steel material of muzzle brake were obtained. The result shows that the using of TC4 can reduce the mass of muzzle brake in service conditions, then it can reduce design complexity of other components.
