摘　　要：聚异氰氨酸酯噁唑烷酮(polyisocyanateoxazodone,POZD)是一种弹性材料,可以在结构表面形成高强度和高弹性涂层,具有减轻不同结构冲击和爆炸的潜力。为研究POZD作为涂层时梁板式钢结构防护门的抗冲击性能,采用数值模拟方法对该门扇在6级载荷作用下的动态响应过程进行研究,分析面板厚度、工字钢型号变化时对门扇抗冲击性能的影响。将裸门扇和表面喷涂POZD门扇进行对比,结果表明,当载荷和门扇结构确定时,可通过涂覆POZD涂层提高结构抗力。基于以上结果,设计出新型轻量化高抗力复合材料防护密闭门,相较于原始防护门结构,质量减小32.5%,最终通过新型复合材料防护门在冲击载荷作用下的变形试验研究,验证了数值计算结果的可靠性。Polyisocyanateoxazodone(POZD)is elastomeric material that can form high-strength and high-elastic coatings on the surfaces of structures,has the potential in impact and blast mitigation of different structures.In order to study the impact resistance performance of a beam plate steel structure blast door with POZD coating,the dynamic response process of the blast door under level 6 load was studied by numerical simulation.The influence of the number of double T-steel and thickness of the panel on the impact resistance of the door was analyzed.Compared with a bare door and a surface sprayed polyurea door,results show that the POZD coating can improve the impact resistance performance of the structure.Based on the result,a new lightweight composite material of the blast door with high resistance was designed.Compared with the original blast door structure,the mass was reduced by 32.5%.The reliability of the simulation results was validated with deformation test of the new composite material blast door under impact loading.
