| Abstract: |
| 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.m²), 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. |
