制式定装炮弹拔弹力的计算和控制方法

Computation and Control of Extracting Bullet Force for Authorized Fixed Loading Shell

制式定装炮弹的拔弹力是炮弹设计和装配中需要控制的重要性能指标。以前关于拔弹力的计算资料较少,通过对控制拔弹力的意义和控制方法以及影响因素的分析,利用动力学原理建立了计算方法并与实验测定值作了对比,证明该方法具有一定使用价值。

The extracting bullet force of authorized fixed loading shell is an important performance in shell design and assembly. There wasn＇t much information about the extracting bullet force computation earlier. Analysis were conducted on significance and methods of extracting bullet force control as well as the influential factors, the computational method was built by principle of dynamics and compared with experimental measure, the method is proved to be effective.
