摘要
针对矿用可移动式救生舱,利用ANSYS和LS-DYNA软件建立了救生舱壳体的三维有限元模型.模拟等效三角波爆炸冲击载荷作用下矿用可移动式救生舱壳体的动态响应.通过数值模拟,确定救生舱壳体动态承载能力和变形模式,给出瓦斯/瓦斯煤尘爆炸超压与救生舱承载能力和变形模式的变化规律,为救生舱设计、抗冲击能力的评价提供理论指导和依据.
A three-dimensional finite element model of movable mine rescue capsule shell has been developed using ANSYS and LS-DYNA software in this study.A simulation of the dynamic response of mine movable lifesaving cabin shell under the action of equivalent triangle wave explosion impact load has been conducted.Through the numerical simulation above,the study has defined the dynamic bearing capacity and the deformation mode of capsule shell,obtained the characteristics of the overpressure of gas/gas and coal dust explosion,the variation of bearing capacity,and the deformation mode of rescue capsule.The study provides a theoretical guidance and basis for the rescue capsule design and the anti-impact ability evaluation.
