炮箱是转管自动机的重要零件,在后坐过程中承受巨大冲击载荷.根据武器系统的轻量化要求与高强度需要,针对不同比厚度的炮箱,采用有限元分析方法,通过路径规划与数据映射,对轴向与周向的应力应变分布规律及其对炮箱可靠性以及对曲线导轨导转精度造成的影响进行研究;根据拓扑优化结果优化炮箱结构,经过对比,优化后的炮箱在满足轻量化与高强度要求方面具有更好的结构特征与应力分布.
Gunbox is an important part of automatic pipe-handling machine and can bear a huge impact load during the recoil process.According to the requirements of light weight and high strength of weapon system, the finite element analysis method and the path planning Data mapping, the stress and strain distribution in the axial and circumferential direction and its influence on the reliability of the gun case and the guidance accuracy of the curved guideway are studied. The structure of the gunbox is optimized according to the topology optimization results. After comparison, the optimized gun The box has better structural features and stress distribution in meeting the requirements of lightweighting and high strength.
