摘要
为了提高弹丸侵彻明胶靶标的虚拟试验能力,采用了一种无网格方法(SPH法)来进行模拟计算。建立了弹丸与明胶靶标的有限元模型,分析模拟了SPH法中的粒子密度与弹丸入射角对侵彻速度衰减与侵彻深度的影响,并得出了满足误差要求的仿真与试验数据对比曲线。结果表明,SPH方法在处理高速侵彻问题上是一种有效的有限元方法。
In order to improve the virtual test capabilities of the projectile penetrating gelatin targets, using a gridless method （SPH method） to simulate the calculation. First, this paper establish a finite element model of the projectile and gelatin targets, to simulate the SPH method in the particle density and the projectile angle of incidence on the penetration speed attenuation and penetration depth, and draw a contrast curve of simulation and test data to meet the error requirement. The results show that the SPH method to deal with the problem of high-speed penetration is an effective finite element method.
