노선 환경에 따른 고무 타이어 경전철 차량 실주행 진동 영향 분석 연구

초록

The light rail train using rubber tires have low noise and low vibration, which improves ride comfort and eliminates the risk of derailment. In the case of light rail train with rubber tires applied, the acceleration and deceleration and rapid curve and high ratio slop driving performance are very excellent, making it possible to construct a shorter distance between stations compared to the existing metro and a sharp curve and high ratio slop route like general vehicle roads. Therefore, it has been expanded to solve the urban traffic problem. However, in the case of tires for light rail train, there is a great challenge in technology development for securing tire lifespan and durability due to the rapid curve and high ratio slop routes. Therefore, in this study, in order to develop a rubber tire for light rail train with high durability and long life, while maintaining the advantages of low noise and low vibration rubber tires for short inter-station distances and sharp curves and high ratio slop routes similar to general vehicle roads. The information, which are the curve radius and curve section of the currently running light rail line, the time required between stations and the distance between stations, is analized with measuring data through the actual light rail train test; the average speed information between stations and the the axle's acceleration vibration during actual driving.
