摘　　要：目的解决高射速转管武器供弹系统在启动阶段功耗较大、冲击载荷显著的技术难题。方法提出一种集成浮动链轮载荷分离机构的链式弹箱结构。通过建立多体动力学模型,对比分析有无浮动链轮机构的动力学特性差异,揭示该机构对无链供弹箱启动阶段动力学特性的调控机制。结果浮动链轮机构的载荷分离作用可以将供弹系统启动阶段最大功率降低30.76%,链轮链条最大冲击力降低48.7%。结论浮动链轮机构的引入可以实现功率调控和冲击抑制的目标,且该机构的载荷分离作用使主动链轮呈现变转动惯量特性(波动范围为±0.04 kg·m^(2)),可以在机构失效前有效降低系统惯性负载。该研究不仅为转管武器供弹系统设计提供了新的技术路径,而且提出的变惯量调控方法对动态链传动系统的优化设计具有一定的指导意义。The work aims to solve the technical problem of high power consumption and significant impact load during the start-up phase of the high firing rate rotary tube weapon feeding system.A chain magazine integrated with a floating sprocket load separation mechanism was proposed.By establishing a multi-body dynamics model,the differences in dynamic characteristics between mechanisms with and without floating sprocket were compared and analyzed,revealing the regulatory mechanism of this mechanism on the dynamic characteristics of the non-chain feeding box during the start-up phase.The load separation effect of the floating sprocket mechanism could reduce the maximum power of the ammunition feeding system during the start-up phase by 30.76%and the maximum impact force of the sprocket chain by 48.7%.The introduction of a floating sprocket mechanism can achieve the goals of power regulation and impact suppression,and the load separation effect of this mechanism causes the active sprocket to exhibit variable rotational inertia characteristics(fluctuation range of±0.04 kg·m^(2)),which can effectively reduce the inertial load of the system before the mechanism fails.This study not only provides a new technical path for the design of the feeding system of the rotary tube weapon,but also proposes a variable inertia control method with certain guiding significance for the optimization design of the dynamic chain transmission system.
