120km/h급 화차용 차축베어링 내구성능시험을 위한 수명 해석

Axle bearings applied to the railway vehicle to support the vehicle body and transfer the load to the ground. Therefore, durability of the load is one of the most important performance in axle bearings. For this reason, the durability performance and verification is required prior to the actual vehicle application. According to this result, establish a technical assessment based on the analysis of AAR durability test condition.
