| Abstract: | The method to build a finite element model for the pick cutting rock was discussed.The single pick on the cutting heads of longitudinalaxis roadheaders cutting rock was simulated.The finite element model was built in hypermesh,and solved by the LS_DYNA971.The influences of resistance on different cutting angle and the relations between cutting thickness and cutting energy consumption in different cutting angle were discussed,which were also compared with the commonly used formula of the pick cutting resista... |
