某型重机枪稳定性模型研究

摘要

为研究机枪重量减轻对稳定性的影响,以某型重机枪为研究对象,建立了机枪纵向射击和横向射击的稳定性模型并计算出了稳定极限角.从实际出发全面的分析了各个设计参数对纵向射击和横向射击时稳定极限角的影响,通过Matlab编程计算出主要参数与稳定极限角的关系曲线,以及为达射击稳定所需施加的抵肩力及所加配重大小,得出了相应的结论并提出了改进射击稳定性的措施.为机枪的稳定性论证及改进打下了良好的基础.%To study the stability of a Heavy Machine Gun on the effect of weight reduction,the model of the machine gun in enfilade crosswise shooting is established. The impaction from design parameters to stability limiting angle in enfilade crosswise shooting is analyzed comprehensively and actually. Through program in Matlab,the curve between the main design parameters and stability limiting angle,the needed shoulder force and bob-weight are calculated. Corresponding conclusion has been obtained. And some improvement measure about firing stability has been proposed. It lays a good foundation for the stability demonstration and improvement of machine gun.
