【 摘 要 】

The paper describes a quad bike multi-body model intended to extract maximum dynamic forces acting on the vehicle frame. This complex full-vehicle model includes all essential systems such assuspension, steering, frame, power train, brakes, payload, as well as tire-road interaction model. A number of the quad bike operation events has been simulated. Time histories of the forces acting on the vehicle frame and tire contact patch have been analyzed and load cases with maximum forces have been extracted for subsequent finite-element analysis of the frame. In case the sufficient number of the events is simulated, the load cases can be used in the design optimization process, such as topology optimization, at early stages of the frame development.
