철도차량 차축의 피로강도 설계방법

초록

Railway axles are one of the most important components in railway vehicle with regard to safety, and it is an important research area to verify safety of fatigue strength of railway axle for minimization of derailment of railway vehicle by failure of axles. The axles are subjected to various loads such as vertical, horizontal and traction load, and these are simultaneously exerted when vehicles are running. Therefore, each country are standardized fatigue design method to verify safety of railway axles. This study is to review the standard of fatigue design method such as Japanese (JIS E 4501) and Europe (EN 13103) standard, and to analyze the characteristics and difference of fatigue design method.
