摘要
建筑物或者部件会受到地面上的爆炸和水下的冲击破坏,为承受这种极端破坏,对它进行防护就显得尤为重要。文中介绍了聚脲的材料性能、抗冲击和抗爆性能试验研究,总结了对聚脲有限元分析的研究进展。结果表明聚脲在爆炸防护和结构加固技术等方面有着优异功能,但目前对聚脲的研究还局限于试验分析,理论还相对较少,最后文中对聚脲在结构中的应用进行了展望和总结。
Buildings and components can be damaged by explosions on the ground and underwater impacts,which should be protected from such extreme damage.This article introduces the experimental research on the material properties,impact resistance,and explosion resistance of polyurea.The research progress on finite element analysis of polyurea is summarized,and the results show that polyurea has excellent functions in explosion protection and structural reinforcement technologies.However,current research on polyurea is still limited to experimental analysis without the theory.Finally,the application of polyurea in structure is prospected.
