Abstract
For evaluating the safety of the 220t dump truck cab, the roll-over protective structure/falling object protective structure with welding frame made up square steel tube is tested. The finite element model of the frame is developed. The static loading and impact loading simulations are launched by ABAQUS with ISO standard methods. The results show that all parameters accord the requirement. The welding frame cab can survive and protect the operator in roll-over or falling situation. It is a feasible, economical and flexible scheme for heavy-duty dump truck.
