A Study on Fatigue Crack Growth of an EMU Wheel due to Repeated Rolling Contacts
전동차 차륜의 반복 구름 접촉에 의한 피로균열 전파에 관한 연구
Abstract
The EMU wheel is one of the most important component for the vehicle safety. For the tensile, fracture toughness and crack propagation tests, several specimens were collected from actual wheels. FEM ,analysis also was performed on the crack that was assumed to be 15 mm in depth under the wheel tread surface. The stress intensity factors
