Abstract

Ride comfort of a vehicle can be utilized to maintain the track geometry and track irregularities because ride comfort of the rolling stock is affected by the characteristics of the vehicle and track. Ride comfort was evaluated according to the measured floor acceleration data of vehicles for a Korean high speed line as well as European high speed lines using Continuous comfort method which can be applied to track maintenance. The exceedance distribution of the ride comfort was quantitatively analyzed by the vehicle speed, the ride comfort of the Korean high speed line was compared with that of European high speed lines. It is shown that the ride comfort of Korean high speed line is better than that of European high speed lines, which indicates that the Korean track geometry and track irregularities are properly maintained.

차량의 승차감은 차체의 성능 뿐만 아니라 궤도의 특성에 의해서도 영향을 받게 되므로, 궤도선형 및 궤도틀림의 관리를 위하여 차량의 승차감 평가결과를 이용한다. 본 논문에서는 차체의 진동가속도 계측데이터를 이용하여 궤도유지보수와 상관성이 있는 Continuous comfort 승차감 평가방법을 통해 국내 경부고속철도노선 및 유럽 고속철도노선에 대한 승차감 평가를 수행하였다. 승차감 평가결과를 속도대역 별로 구분하여 국내외 고속철도노선의 승차감 분포현황을 정량적으로 분석하고 승차감 수준을 비교하였다. 국내의 경부고속철도의 승차감이 유럽 고속철도노선에 비하여 다소 우수한 것으로 평가되었으며, 이를 통해 국내 고속선의 궤도선형 및 궤도틀림의 관리가 적절하게 수행되고 있음을 유추할 수 있었다.
