摘　　要：为提高矿用救生舱的碰撞安全性,设计一种泡沫铝填充矿用救生舱。利用ANSYS Workbench的参数优化模块,以舱体的加速度、变形及吸能大小为优化目标,对舱体的结构参数和泡沫铝的材料性能参数进行优化。对优化后的泡沫铝救生舱的碰撞安全性进行分析,结果表明泡沫铝救生舱在质量和最大等效应力均有所降低的前提下,泡沫铝救生舱碰撞时的最大变形和最大加速度得到显著降低并且舱体吸收的能量得到大幅提升,证明泡沫铝填充救生舱具有更佳的碰撞性能可以提高其安全性。In order to improve the crash safety of the mine rescue cabin,a new type of mine rescue cabin filled with aluminum foam was designed.Using the parameter optimization module of ANSYS Workbench,the acceleration,deformation and energy absorption of the rescue cabin were taken as the optimization objective.The structural parameters of the cabin and material performance parameters of aluminum foam were optimized.The crash safety of the optimized aluminum foam rescue cabin was analyzed.The results show that,under the premise that the mass and maximum stress of the aluminum foam rescue cabin are sure to be somewhat reduced,the maximum deformation and maximum acceleration of the foam aluminum rescue capsule are significantly reduced,and the energy absorbed by the cabin is greatly improved.It is proved that the aluminum foam rescue cabin has better crash safety.
