Experimental Study for Dynamic Behaviors of the Rubber-Tired Light Rail Vehicle on the Minimum Curvature

초록

The Korea Railroad Research Institute developed the Korean-standardized rubber-tired light rail vehicle (K-AGT) based on the Korean Standardized Specifications, and built the 2.4km-test track to evaluated the performance and safety of the K-AGT. In this paper, when the K-AGT ran on the minimum curvature (radius 40m) of the 2.4km-test track in driverless mode, translational and rotational vibration accelerations were measured on floor levels and seat surface in the passenger compartment. The peak-to-peak accelerations in vertical and lateral direction, and stationary lateral accelerations were analyzed. Simultaneously, pressures of air suspensions supporting the passenger compartment were measured. Based on the results, it was evaluated whether the K-AGT can give a comfortable and stable public transportation service on the minimum curvature.
