Application of SPH in numerical simulation of roadheader hard rock cutting

摘要：

　　The yaw rock-breaking processes of roadheader single pick at different positions have been simulated by using LS-DYNA,and the dynamic process that pick-shaped cutters cut hard-rock has been analyzed with the technique of SPH(Smooth Particle Hydrodynamics).It has been fotmd that separating rock into smooth particle hydrodynamics(SPH) units can effectively simulate and analyze deformation,damage and other phenomena of rock to lay a foundation of pick design,processing and failure modes analysis.The results of calculations show that this kind of new algorithm is feasible and effective to simulate rock penetration and pick mechanics problems.
