Modelling rollover behaviour of exacavator-based forest machines
This poster presentation provides results from analytical and computer simulation models of rollover behaviour of hydraulic excavators. These results are being used as input to the operator protective structure standards development process. Results from rigid body mechanics and computer simulation methods agree well with field rollover test data. These results show that lateral energy levels absorbed by the rollover protective structures of typical excavators are similar to those of crawler tractors of the same mass. Excavators with cab risers can experience sigdicantly higher levels of energy during rollover events.
