摘　　要：通过对子母弹抛撒作用过程和子弹抛撒加速度理论分析,开展中心爆管式子母弹子弹抛撒加速度估算模型研究,利用有限元仿真模拟和子母弹静态抛撒试验对模型进行验证,结果表明该模型的估算精度能够满足工程要求。该方法可以利用较少的典型工况试验数据,获得适用于一般工况的中心爆管式子母弹子弹抛撒最大加速度,对提高中心爆管式子母弹设计效率,降低研究费效比具有重要意义。This study aims to investigate a method to estimate the maximum acceleration of submunition projectile scattering by utilizing the structural parameters of center bursting tubular submunition and the performance parameters of scattering agent.By analyzing the scattering process and the acceleration theory of submunition projectile scattering,the research on the estimation model of submunition projectile scattering acceleration for center bursting tubular submunition was carried out.The finite element simulation and static scattering experiment of submunition were conducted to verify the estimation model,and the results showed that the estimation accuracy of the model can meet the engineering requirements.This model can use a small amount of typical working condition test data to obtain an approximate value of the maximum acceleration of submunition projectile scattering for general working conditions.It is of great significance to improve the design efficiency of center bursting tubular submunition and reduce the cost-effectiveness ratio in research.
