针对西部地区的特殊地理情况,以矿井救生舱顶面在坍塌载荷作用下的动态响应为研究对象,应用三维设计软件Solidworks、隐式有限元分析软件ANSYS前处理和动力学分析软件LS-DYNA求解器等软件,建立了救生舱有限元模型并进行结构化网格划分完成求解及后处理工作,通过数值仿真分析,得到不同时刻下矿用救生舱位移和应力的瞬态分析结果。分析结果表明:整舱顶部前后中央方位应力超出了材料的屈服极限而发生坍塌变形,但并不会造成致命的塌陷破坏事故。
Aiming at the special geographical situation in the west of China, the dynamic response of the top surface of the rescue team under the collapse load is taken as the research object. The three-dimensional design software Solidworks, the implicit finite element analysis software ANSYS pretreatment and the dynamic analysis software LS-DYNA The finite element model of the rescue capsule was established and the structured mesh was solved and the post-processing was finished. The transient analysis results of the displacement and stress of the life-saving capsule at different moments were obtained by numerical simulation. The results show that: the azimuthal stress in the center of the top of the entire tank exceeds the yield limit of the material and collapses, but it will not cause fatal collapse accidents.
