弹丸侵彻混凝土目标的热固耦合数值分析
Thermal-Solid Coupling Numerical Analysis of Projectile Penetrating Concrete Target
摘要
Abstract
In order to solve the problem of inaccurate calculation of penetration depth in the process of penetration,taking the projectile-target model as the research object,the projectile-target model was established based on ANSYS/LS-DYNA software to calculate the penetration depth of 35CrMnSi projec-tile penetrating C30 concrete target.With the penetration velocity and angle as the initial variables,33 groups of different working conditions were set up,and the thermo-solid coupling numerical analysis of the penetration process was carried out.The data of projectile temperature field,penetration depth and penetration velocity attenuation were extracted and analyzed in depth.The relationship between tempera-ture rise and penetration depth in the process of projectile penetration was obtained.The results show that:1)in the case of vertical penetration,the warhead erosion increases and the temperature changes more significantly with the increase of penetration velocity;2)in non-vertical penetration,the extreme point of temperature rise shifts from the center of the warhead to the side of the projectile,and the impact angle of the projectile increases,and the temperature rise accelerates and the depth of penetration decreases;3)after the end of penetration,the temperature of the projectile is proportional to the depth of penetration,and the proportion is the same in the same penetration angle.The analysis of temperature field in the process of projectile penetration can improve the accuracy of the prediction model of penetra-tion depth,and the research results can provide reference for the test of penetration fuze.关键词
