Influence of Wheel Diameter Difference on Safety and Stationarity of Vehicles Crawling over the Curved Bridge

Wheel diameter difference has great impact on the operation performance of vehicles which are traveling on the curved bridge. A simulation analysis model was built to analyze the influence of wheel diameter difference on safety and stationarity of vehicles on the curved bridge. The results demonstrate that along with the increase of wheel diameter difference, the security of vehicles on the curved bridge decreases and the vehicles run unsteadily. So the wheel diameter difference should be diminished as much as possible, especially strictly controlling the wheel diameter difference of high-speed vehicles.
