摘要
Abstract
As a new protective coating material,polyurea has important application value in improving the anti-penetration performance of armored structures.Based on Autodyn simulation software and using 2D Lagrange algorithm,this paper studies the dynamic response of polyurea coated composite structures with three different coating methods(anti-projectile surface coating,back-projectile surface coating and double-sided coating)under projectile penetration.The projectile is a cylinder,the material is 20CrMnSi,and the initial velocity is 700 m/s.The target plate material is Q460 steel plate,and the polyurea material is simulated using the Mooney-Rivlin model.The protective performance of different coated structures was evaluated by analyzing indicators such as energy dissipation per unit area density and projectile velocity drop.The results show that the back-coated structure has the best anti-penetration performance,and its energy dissipation per unit area density is higher than other coating methods.Further optimization analysis was carried out by adjusting the ratio of polyurea coating to steel plate thickness.It was found that when the ratio of polyurea to steel plate thickness was about 1∶5,the back-surface coated structure had the best energy absorption effect and anti-penetration performance.This study can provide theoretical basis and simulation support for the optimal design of polyurea coatings in armor protection.关键词
