摘要
为对某大口径火炮不同坡膛锥角时弹丸挤进过程进行对比分析,通过光滑粒子流体动力学法仿真某装药条件下弹带挤进过程。仿真得到挤进阻力和导转力矩,分析产生力矩波动的原因,并提出减轻力矩波动、缓解膛线受力的改进措施。结果表明,该研究能为坡膛锥角对弹带刻槽影响的研究提供参考。
In order to compare and analyze the engraving process of projectile in a big bore gun with different bore cone angles,smoothed particle hydrodynamics(SPH)method was used to simulate the engraving process of projectile band under a certain charge condition.The engraving resistance and driving torque are obtained by simulation,and the causes of torque fluctuation are analyzed,and the improvement measures to reduce the torque fluctuation and relieve the rifling force are put forward.The results show that the study can provide a reference for the study of the influence of the cone angle of the slope bore on the groove of the ammunition belt.
