Ansys/ls-dyna数值仿真技术在井巷工程教学中的应用

Application of Anays/Ls-dyna Numerical Simulation in Roadway Engineering Class Teaching

本文针对井巷工程课程中的爆破方面的理论知识比较抽象,难于讲解和理解的问题,采用Ansys/Ls-dyna数值模拟软件模拟了炸药在岩土中的爆炸过程。从定性和定量的角度描述了炸药爆炸过程中动应力场的演化过程,并对计算结果用图片及动画的形式进行演示,在多媒体教学中起到了较好的辅助作用。

Because the blasting theory is abstract, and is difficult to understand and explain, Ansys/Ls-dyna soft is used to simulate dynamite blasting in rock. According to the simulation results, the dynamic stress field evolution during dynamite blasting is described quantitatively and qualitatively. In the teaching with multimedia technology, the simulation results are playing an important part through pictures and animation effect.
