基于动态稳定原理的机枪结构优化

Structural Optimization of Machine Gun Based on Dynamic Stability Concept

提高机枪的射击精度是机枪结构优化的最终目标。分析了影响机枪散布精度的主要因素,基于动态稳定性的观点,建立了机枪结构优化模型,并对散布精度对设计变量的灵敏度进行了分析。通过对某型机枪优化设计,结果表明:该方法正确可行,对于自动武器的结构修改有一定的指导意义。

Improving the firing accuracy is the final aim in the structural optimization of machine guns. The main factors which affect the dispersion accuracy of machine guns were analyzed. Based on the concept of dynamic stability, a structural optimization model was built up and the sensitivity of dispersion accuracy to design variables was analyzed. The optimization results of a type of machine gun show that the method is valid, feasible and can be used as a guide to the structural optimization of other automatic weapons.
