摘要
以钛合金材料代替传统炮钢材料,设计一种基于3D打印的30 mm口径新型复杂结构航炮炮口制退器,有效减轻其质量,提高火炮的射击稳定性。根据经典内弹道理论,计算出弹丸出膛口膛内的温度、速度以及压强的分布,确定壁面所受的最大压强,进行多种制退器结构力学分析,比较其总变形、应力云图。结果表明:新型钛合金炮口制退器不仅能实现轻量化,还增强了承载能力。
In order to reduce the weight of muzzle brake and improve the firing stability of artillery,a new complex structure of 30 mm cannon muzzle brake based on 3D printing was designed and titanium alloy was used to replace the traditional gun steel material.The temperature,velocity and pressure distribution in the chamber were calculated by the classic internal ballistic theory to determine the maximum pressure on the wall surface,and the mechanical analysis of each structure was carried out to compare its deformation and pressure cloud maps.The results show that the new type of titanium alloy muzzle brakes can not only reduces its own weight,but also improves its bearing capacity.
