煤矿救生舱在轴向爆炸载荷作用下的运动趋势研究

Study on movement tendency of colliery rescue chamber at axial explosive load

为了研究煤矿井下救生舱受到轴向爆炸载荷作用时的运动过程,使用Patran软件建立了救生舱及巷道的三维有限元模型,在考虑固流耦合问题的条件下,导入Dytran软件对舱体的运动过程进行了仿真。仿真结果表明,使用Patran及Dytran软件可以有效地对舱体的运动趋势进行仿真,得到较为准确的仿真结果。

To study the movement of colliery rescue chambers at the axial explosive load, software Patran was applied to build the 3D model of a rescue chamber and laneways. Taking solid-liquid coupling into account, software Dytran was introduced to simulate the movement of the rescue chamber. The simulation results indi- cated that Patran and Dytran could be applied to simulate the movement tendency of the rescue chamber with accurate simulation results.
