摘　　要：矿用救生舱是煤矿瓦斯、煤尘爆炸事故时,保护煤矿工人的重要应急避险装备。需要救生舱舱体能抵抗冲击波、石块的冲击,且具有优异的隔热性能。通常设计矿用救生舱时,都是增加构件厚度或对救生舱结构进行优化,研究性能已经开发优化到了瓶颈。而该文章采用负泊松比材料填充进矿用救生舱夹层内,利用其轻质化、隔热、隔振和抗冲击性能优良的特点,提升整体救生舱的抗冲击能力和隔热能力。通过爆炸瞬态热分析、热力耦合冲击性能分析、碰撞冲击响应分析等来验证负泊松比填充矿用救生舱其优越的安全性能。Mine rescue cabin is an important emergency equipment for protecting coal miners in cases of gas and coal dust explosion accidents in coal mines.It is necessary that mine-used lifesaving cabin body can withstand impacts of shock waves and rocks,and have excellent thermal insulation performance.Generally,when designing a mine rescue cabin,it is necessary to increase thickness of components or optimize its structure.Studying its performance has been developed and optimized to bottleneck.Here,a negative Poisson’s ratio material was used to fill interlayer of mine rescue cabin,and its excellent characteristics of lightweight,heat insulation,vibration isolation,and impact resistance were utilized to improve anti-impact performance and thermal insulation ability of the overall rescue cabin.The superior safety performance of negative Poisson’s ratio material-filled mine rescue cabin was verified through explosion transient thermal analysis,thermodynamic coupled impact performance analysis and collision impact response analysis.
