Car Body Durability of Rubber-Tired Light Rail Vehicle in the Two Dangerous Events

초록

For the Korean-standardized rubber-tired light rail vehicle, durability of car body was evaluated in dangerous events which were unbalance-loaded train running and flat-tired train running. We have analyzed stresses of the car body under unbalanced-loaded weight condition by using finite element method. We have also measured dynamic stresses of the car body for the two dangerous event, while the train was running in about 2.4km length test track. Experimental results have verified the durability of the car body in the two dangerous events.
