摘要
为研究不同质量和不同速度下明胶鸟弹的数值建模方法,开展明胶鸟弹撞击力传感器试验。试验过程中明胶鸟弹呈现类似流体状破碎和前端破裂后残余部分回弹的两种失效模式;在数值建模中,对破碎呈流体状的明胶鸟弹选用SPH方法离散及状态方程本构模型,对前端破裂后残余部分回弹的明胶鸟弹选用拉格朗日方法离散及含失效的弹塑性本构模型,并依据试验结果分别对其本构参数进行反演,计算结果与试验结果吻合度较高,验证了该建模方法的合理性;对本构参数适用性进行验证,结果表明,在该设计的明胶鸟弹质量和撞击速度范围内,对于含失效的弹塑性本构模型,不同质量的明胶鸟弹需要不同的本构参数进行建模;对于状态方程本构模型,不同质量与不同速度的明胶鸟弹,需要不同的本构参数进行建模。
In order to study the numerical modeling methods of gelatin bird under different quality and different velocities, the gelatin bird impact force sensor experiment were conducted. It was shown that two kinds of failure modes of the gelatin bird that fluid-like failure and remaining part rebound after the front end breaks. In numerical modeling, the SPH method of discretization and the equation of state constitutive were used to model the gelatin bird in the case of fluid-like failure; the Lagrange method of discretization and elastic-plastic with damage constitutive were used to model the gelatin bird in the case of remaining part rebound after the front end breaks. According to the experiment results, the constitutive parameters were inverted respectively; the numerical result is in good agreement with the test results. It shows that the modeling method is reasonable. The verification of applicability of constitutive parameters was performed, under the premise of gelatin bird quality and impact velocity range in this paper, it also shows that different quality gelatin bird need different constitutive parameters to model for the elastic-plastic with damage constitutive; gelatin bird of different quality and different velocity need different constitutive parameters to model for the equation of state constitutive.
