摘要:
为提高环境实验舱防爆门抗爆炸冲击性能和吸能特性，基于仿生拉胀内凹负泊松比结构，设计具有双向功能梯度内芯结构的防爆门。运用ABAQUS软件综合分析不同梯度芯层对冲击载荷下防爆门的压溃模式和能量吸收特性的影响，着重探讨不同爆炸载荷下前后面板挠度和芯层能量吸收情况，并通过实验对仿真数据进行验证。研究结果表明：较于传统防爆门结构，改进后的防爆门后面板最大应力值降低约13.45%，防爆门结构比吸能提升27.08%。研究结果可为高抗爆防护结构的设计优化、轻量化防爆装备开发、多功能梯度材料在冲击防护领域的应用提供数据支撑与理论参考，并为航天、军工、车辆电池舱等领域的特种防爆门结构创新提供新的设计思路与工程解决方案。
Abstract:
In order to enhance the anti-blast shock performance and energy absorption characteristics of explosion-proof doors in environmental test chambers,an explosion-proof door with bidirectional functional gradient inner core structure was designed based on biomimetic auxetic re-entrant negative Poisson’s ratio structure.ABAQUS software was employed to comprehensively analyze the effects of different gradient core layers on the crushing mode and the energy absorption characteristics of the explosion-proof door under shock loads.The study focused on investigating the deflection of the front and rear panels and the energy absorption of core layers under various explosive loads,with experimental validation of the simulation data.The results indicate that compared to traditional explosion-proof door structures,the improved explosion-proof door reduces the maximum stress on the rear panel by approximately 13.45% and increases the specific energy absorption of the explosion-proof door structure by 27.08%.These findings provide data support and theoretical basis for the design optimization of high-anti-blast protective structures,the development of lightweight explosion-proof equipment,and the application of multifunctional gradient materials in shock-protection fields.These findings also offer new design concepts and engineering solutions for innovative special explosion-proof door structures in aerospace,military,and vehicle battery compartment applications.
