针对大口径迫击炮自动装填系统的功能和需求,设计一种传动性能较好的齿形链式回转弹仓,并针对性地设计了前后限位器,使其能够较好地储存和保护迫击炮弹。其次,链传动特有的多边形效应将导致弹仓回转的不稳定性,为此通过建立弹仓的虚拟样机模型,对弹仓进行动力学分析,得出在极限工况下的供弹精度,结果均满足最初的设计指标要求,对弹仓结构的研究和分析具有一定的理论指导意义。
Aiming at the function and demand of large-caliber mortar automatic filling system, a kind of chain-shaped rotary magazine with good transmission performance is designed and the front and rear stoppers are designed in order to store and protect them better Mortar shells. Secondly, the polygon effect peculiar to the chain drive will lead to instability of the rotation of the magazine. Therefore, through the establishment of the virtual prototype model of the magazine, the dynamic analysis of the magazine is carried out, and the accuracy of feeding in the extreme condition is obtained. The result All meet the initial design requirements of the magazine structure of the study and analysis has some theoretical significance.
