Harvester Performance
Video 9 shows simulation a combine harvester header simulation, including hay breakage and
plastic deformation of the stems. Particles were modeled using Rocky DEM custom flexible
fiber particle type to model the crop.
Wood Chipper Efficiency
In the example shown in Video 10 below, the goal was to evaluate the chipping efficiency for
different disk rotational speeds as well as to assess if clogging would happen when changing
the wood tonnage.
Wood branches were modeled using custom flexible fibers, and the wood chopping was modeled
using the fiber breakage model.
