| Abstract: | By using a coupling model of vehicle-track,this paper calculates and analyzes the various safety index of the dynamic for the vehicle with different velocities after the overhaul of track by largescaled machines.Meanwhile,a spot test focusing on the train derailment coefficient,eccentric load rate and the lateral displacement of the rails was carried out as the train is running in different speeds.These measurements will provide both academic and practical bases for the inaugural speed of the train after the overhaul of the track. |
