| 摘 要： | 为减小炮口制退器质量并能耐烧蚀，设计一种复合结构的炮口制退器。分别采用炮钢和钛合金材料组成炮口制退器的内、外层结构。以带炮口制退器的炮口流场的瞬态动载荷为计算条件，利用单向流固耦合方法对复合结构炮口制退器进行强度分析。分析结果表明：复合结构炮口制退器可满足强度要求，且质量明显小于全炮钢炮口制退器，可为提高炮口制退器的性能提供一种新的设计思路。

| Abstract: | A muzzle brake with composite structure is proposed to reduce the mass and resist ablation. The muzzle brake with composite structure is composed of inner structure and outer structure, whose inner structure is made of gun steel and whose outer structure is made of titanium alloy. Based on the transient dynamic load which is calculated from muzzle flow field with muzzle brake, the strength analysis of muzzle brake with composite structure is operated via fluid solid coupling method. The results show that the muzzle brake with composite structure can meet the required strength, and its mass is much smaller than that of muzzle brake which is made of gun steel, it opens a new avenue for the design strategies of high-performance muzzle brake. |
