圆锥头弹体冲击复合材料层合板数值模拟
|
摘要
采用ABAQUS软件建立了圆锥头弹体正冲击复合材料层合板的有限元模型,并与已有文献结果进行对比验证了模型的可靠性,进而研究圆锥头弹体以不同的入射角度冲击复合材料层合板时初始速度与剩余速度的关系、复合材料层合板的破坏形态及弹体发生跳弹的规律。结果表明:弹体以90°入射角冲击复合材料层合板,在距离临界速度较大时,弹体的剩余速度与初始速度呈线性关系;不同的初始速度对复合材料层合板的损伤面积和破坏机制也不相同;弹体的入射角度越小、复合材料层合板越厚,越容易产生跳弹现象,并给出了入射角度和铺陈层数对跳弹现象的影响规律。该研究可为各种防护装备的设计和优化提供参考。
A finite element model of conical projectiles impacting composite laminated plates had been established by using Abaqus software.The reliability of the model was verified by comparing with the existing literature.And the relationship between the residual velocity and the initial velocity of the conical projectile at different angles of incidence,the failure mode of the composite laminated plate and the rules of projectile ricochet were studied.The results show that when the projectile impacts the laminates at 90°and from the critical velocity is larger,the residual velocity of the projectile is linearly related to the initial velocity.Different initial velocities can lead to different damage areas of the laminate and different mechanisms of damage.The smaller the incident angle of the projectile,the thicker the laminate,the more prone to ricochet,and the influence of the angle of incidence and the number of laying layers on the ricochet is given.The study can provide a reference for the design and optimization of various protective equipment.
