랜덤진동을 고려한 철도차량 주 변압기의 내구 특성 평가 = Evaluation of the Durability Characteristics of the Railway Vehicle Main Transformer Under Random Vibration

다국어 초록 (Multilingual Abstract)

This study conducted finite element analysis of the railway vehicle main transformer, which is a core component of railway vehicles. The purpose of this analysis is to evaluate the structural integrity and fatigue durability of the main transformer during random vibration by applying various analysis techniques. We performed static structural and fatigue analyses by applying the technical standards of railway vehicles and the detailed contents of EN 12663-1. The results of the static analysis confirmed that the maximum equivalent stresses generated in all the load cases were satisfied within the yield strength of the material. In addition KS C IEC 61373 was applied and Miner's rule was used to calculate the fatigue life. Based on the evaluation, the total damage index was 0.4381 according to Miner's rule.
