The invention discloses a bogie fault diagnosis method integrated with multiple sensors. The method comprises the following steps: synchronously acquiring vibration impact signals of the multiple sensors installed at fault-prone positions of a bogie; calculating a phase difference of the vibration impact signals of each sensor relative to the vibration impact signals of a certain sensor; according to the phase differences, positioning fault positions; according to the phase differences, performing phase shifting on the vibration impact signals of each sensor through a phase shift technology and carrying out signal integration; and calculating a maximum value of integrated signals and carrying out quantified diagnosis on faults. The fault diagnosis method provided by the invention can improve fault position locating and grade-alarm precision and sensor redundancy and can realize diagnosis of the faults of non-rotatable parts of the bogie.
