The wheel wear prediction of a Korea High Speed Train using a FE-analysis

유한요소해석을 이용한 한국형 고속철도 차량의 차륜 마모 예측

It is difficult to apply the Hertz theory to the wheel-rail contact problem which has the complicated geometric form and plastic deformation. Therefore, we perform the elastic-plastic FE analysis and compare the results with those of Hertz theory. Kalker's simplified theory of rolling contact is used to discretize the contact patches and calculate local traction and slip. The wear volumes are calculated using Archard wear equation.
