Running gear, as the key equipment of metro vehicles, its hazard evaluation is important for metro operation. But the most existing evaluation methods lack entire evaluation and over-reliance on subjective experience. Therefore, a complete hazard evaluation index system of running gear was established based on the inspection data and expert assessment. And for considering both quantitative and qualitative aspects, the hazard state of running gear was assessed by extension theory and entropy weight method. And specific application to a running gear at different time proved that the proposed method is practicable.
