The invention belongs to the technical field of wheel axle flaw detection, and particularly relates to a method, a device and equipment for determining abnormity of a wheel axle and a medium. The method comprises: acquiring an ultrasonic signal of a target axle; determining a plurality of intrinsic mode functions according to the ultrasonic signal; determining the sound wave features according to the plurality of intrinsic mode functions; and determining whether the target axle is abnormal or not according to the sound wave characteristics. According to the method, the interference of background noise can be automatically and efficiently eliminated from heavy-load railway wagon axle anomaly detection, the dependence on professional knowledge is reduced, the fault diagnosis efficiency is improved, and manpower is liberated from heavy fault recognition and is more put into secondary verification.
