    Aug 06, 2014 · Grain kernels are finite and discrete materials. Although flowing grain can behave like a continuum fluid at times, the discontinuous behavior exhibited by grain kernels cannot be simulated solely with conventional continuum-based computer modeling such as finite-element or finite-difference methods. The discrete element method (DEM) is a proven numerical method that can model discrete

    A bucket control mechanism is developed for the simulation of rock pile scooping by wheel loaders. By measuring the reaction forces from the scooped rock pile by a six axis force sensor installed into this mechanism, the reaction force model can be obtained and its parameters are identified. By using the obtained model for controlling actual wheel loaders, efficient scooping can be expected.
