【Abstract】 Computation of the vehicle’s bilateral distance is presented. By the vehicle-track dynamic coupled model, changes in safe boundary of #3 Guangzhou Metro are analyzed. It is confirmed that the constructed boundary may satisfy the requirement with a speed of 130km/h, though it is designed in accord with a speed of 80km/h. So it is not necessary to change the boundary dimension for ensuring the train running safely and steadily.更多还原
