摘要：

The load of C80B gondola freight car body is analyzed in railway. Measured load spectra of fatigue key parts of the freight car body are got. According to the measured load spectra, combined with the load-strain transfer coefficient, the fatigue damage of freight car body is calculated. Then fatigue life of C80B freight car body is predicted by using fatigue cumulative damage theory.
