摘要
为了提高工程爆破课程教学效果,提出将光滑粒子流体动力学-有限元(SPH-FEM)耦合法数值模拟用于课程教学。首先,阐述了SPH-FEM耦合法的基本原理;然后,以集中装药爆破为典型案例展示了建模过程、耦合检验和模拟结果;最后,将模拟结果融入实际教学以探究SPH-FEM耦合法数值模拟在工程爆破教学中的应用效果。研究结果显示,SPH-FEM耦合法能够充分结合SPH粒子和FEM网格各自优势;采用SPH-FEM耦合法数值模拟可以直观呈现集中装药爆破历程;可以帮助学生领悟和掌握专业知识,提高学习积极性。
To improve the teaching effectiveness of engineering blasting courses,it was proposed to use the Smoothed Particle Hydrodynamics-Finite Element Method(SPH-FEM)coupling algorithm numerical simulation in engineering blasting course teaching.Firstly,the basic principle of SPH-FEM coupling algorithm was elaborated;Then,the modeling process,coupling inspection,and simulation results were demonstrated using the example of a concentrated charge blasting;Finally,the simulation results were integrated into practical teaching to explore the application effect of SPH-FEM coupling algorithm numerical simulation in engineering blasting teaching.The research results show that the SPH-FEM coupling algorithm could fully combine the advantages of SPH particles and FEM grids.The SPH-FEM coupling algorithm numerical simulation could visually present the blasting process of the concentrated charge.The use of SPH-FEM coupling algorithm numerical simulation in practical engineering blasting teaching could help students understand and grasp professional knowledge,and improve their learning enthusiasm.
