    Abstract
  • To control effectively the influence of rotational inertia errors in the vehicle collision model on the simulation results, the influence rules were analyzed by perturbation theory. The influence degrees were investigated using the average slope of the pre-impact vehicle speed curve, the pre-impact vehicle speed angle curve, and the pre-impact angular velocity curve. According to the influence degrees, rotational inertia ranges that meet the demand of the simulation result accuracy could be determined. The result shows that when the rotational inertia error is controlled within 7.94%, the relative error of the simulation result is less or equal to 5%.
