The invention discloses a honeycomb-type fault removal and energy absorption device for a rail transit vehicle. The honeycomb-type fault removal and energy absorption device comprises a fault removal and energy absorption device high-rigidity supporting back frame and at least one honeycomb-type fault removal and energy absorption unit, wherein the fault removal and energy absorption device high-rigidity supporting back frame is detachably arranged on a vehicle body of the rail transit vehicle; the honeycomb-type fault removal and energy absorption unit is fixed on the fault removal and energy absorption device high-rigidity supporting back frame in a screw joint manner, and is used for absorbing impact energy generated by impact through plastic deformation; and the honeycomb-type fault removal and energy absorption unit comprises a honeycomb structure containing cavity and a honeycomb structure arranged in the honeycomb structure containing cavity. According to the honeycomb-type fault removal and energy absorption device, before obstacles have rigid impact with the vehicle body, one part of energy is absorbed through the honeycomb-type fault removal and energy absorption unit in a manner of additionally arranging the honeycomb-type fault removal and energy absorption unit on the fault removal and energy absorption device high-rigidity supporting back frame, so that the relatively large impacting force on the vehicle body is weakened, and furthermore, damages to the vehicle body by the obstacles are reduced.
