基于ANSYS数值模拟的密闭墙抗爆冲击安全性分析
Safety Analysis of Anti-explosive and Anti-impacted Airtight Wall Based on ANSYS Numerical Simulation
摘要
Abstract
To promote the safety of mine production and provide scientific basis for the design of airtight wall,taking the antiimpact airtight wall in Shenhua Group as the object,we establish the calculation model of airtight wall through ANSYS Workbench software,set four different loading curves to impact the wall,and use transient analysis to obtain the stress state of the wall under four kinds of different sustained explosion load.By analyzing the force distribution of the wall,we obtain the safety under the impact of a certain strength.The numerical simulation results show that the safety performance of the airtight wall is good under a given load.The dangerous areas of the airtight wall that is easy to be damaged are mainly at the back of the innerwall and the cuttings,and rebar can be added to the inner wall to reduce damage.关键词
