철도차량용 차축베어링의 가속수명시험방법

초록

Railway axle bearings are an important part to support and slip the axle of a railway running at high speed. Axial bearings require high reliability and stability because If the axle bearing is damaged, it can lead to a railway accident. Therefore, it takes a lot of time and cost for the durability test to confirm the reliability. In this study, we propose a method to solve these difficulties. The acceleration factor is generated using the slope of the S-N curve and Accelerated life testing based on the EN12082 test is used to reduce the time required to determine durability. This test will reduce the time and cost of determining the bearing life.
