| 中文摘要: |
| 枪弹分发是枪弹管理的关键环节之一，目前多采用人工分发的方式，不仅分发效率低，还存在错发、漏发的风险，因此课题组研发了一种基于生物信息识别的枪弹分发装置，设计了一种环形阵列式储弹机构。储弹机构沿环向均布50个锯齿形落弹仓，每个落弹仓可存储30发枪弹；为了提高存储效率，以缩短枪弹的下落时间为设计目标，提取关键结构参数，建立落弹仓结构模型，并进行正交仿真试验。结果表明：过渡斜面及锯齿形斜面的倾斜角度α是影响枪弹下落时间的主要因素，在保证枪弹下落姿态的前提下增大过渡斜面及锯齿形斜面的倾斜角度α能够缩短下落时间；优化后单发枪弹从弹仓口落到弹仓底的下落时间缩短至0.681 5 s，较优化前效率提升12.94%；装满50个落弹仓总耗时为71.00 s，较优化前效率提升7.19%。 |

| Bullet distribution is one of the critical component of ammunition management. At present, manual distribution is predominantly used, leading to low efficiency and risks of misdistribution and omissions. Therefore, a bullet distribution device had been developed based on biometric identification recognition, featuring a circular array storage mechanism. The storage mechanism includes 50 zigzag drop cartridges uniformly distributed along the circumferential direction. Each drop cartridge can store 30 shots. To improve storage efficiency, with the reduction of drop time as the design goal, key structural parameters were extracted, a structural model of the bullet drop cartridge was established, and orthogonal simulation experiments were conducted. The results indicate that the slope angle α of the transition and zigzag inclined planes is the primary factor affecting drop time. Increasing the slope angle α of these planes significantly can shorten the drop time while ensuring proper ammunition dropping posture. After optimization, the drop time of a single bullet from the top to the bottom of the cartridge was reduced to 0.681 5 seconds, representing 1294% improvement in efficiency compared to the pre optimization state. It takes 7100 seconds to fill 50 drop cartridges, which is 7.19% more efficient than before optimization. |
