As the hydraulic excavator is a digging machine, the system analysis considering digging behavior of the soil is important for evaluating the digging performance. To date, the majority of research in digging analysis has focused on using the Discrete Element Method(DEM) which is proposed by Cundall and Strack[1]. Coetzee and Els[2] have demonstrated the validity of the simulation results using
