Evaluation of Static Strength and Fatigue Strength for Bogie of a Korea High Speed Train Including Eddy Current Brake System

A FEM-based analytical approach was used to evaluate the static strength and the fatigue strength of a KHST bogie including eddy current brake system. Calculation was carried out in the fields of linearity and small deformation. The yield strengths were used as criteria for evaluating the static strength and the fatigue limits were used as criteria for evaluating the fatigue strength. The analysis results show that there is not any location that exceeds the allowable criteria.
