Structural Optimization of a Heavy-Duty Truck Based on a Virtual Prototype Model

Abstract:

A virtual prototype whole-body model was built for a tri-axial heavy-duty truck. Selecting the lateral acceleration, roll angle and yaw rate as the evaluation index, the sensitivity of wheelbase and track was analyzed and the coordinates of hard points were optimized. The Hunting behaviors of the optimized vehicle were discussed and compared with that of the original vehicle. It is shown that the roll angle, yaw rate and vertical acceleration of vehicle body and the vertical acceleration at the seat are reduced greatly after optimization. Thus the vehicle structural optimization improves both handling stability and ride comfort.
