피로시험 및 비파괴 검사를 통한 틸팅열차용 주행장치 프레임의 안전성 평가

This paper has performed fatigue and nondestructive test of bogie frame for Korean tilting train. Before the fatigue test, static tests were carried out. From the test, the structural safety was investigated using Goodman diagram. After the static test, the fatigue test were conducted under tilting load conditions. The fatigue test was conducted for 10×10 6 cycles. During the fatigue test, the nondestructive tests using magnetic particle and liquid penetrant were performed at 6×10 6 cycle and 10×10 6 cycle. From the crack detection tests, it was known that there was no fatigue crack in the bogie frame.
