【Abstract】 The total weighing value method for evaluating the vertical smoothness of a vehicle, which was commonly used in this field, and the full probability method for evaluating a pavement damage which was developed by the authors and was more precise compared with the others, were adopted to simulate a real system. The simulating results indicated that there was a strong relationship between vehicle smoothness and its damage to pavement when suspension stiffness, suspension damp, tire stiffness, suspension mass, un suspension mass and speed varied respectively. The results may be used in a vehicle design and optimization to assure the vehicle has both a higher smoothness and less damage to pavement.更多还原
