The invention provides a multistage energy absorption apparatus for a rail vehicle, and belongs to the technical field of passive safety of rail transit vehicles. The apparatus comprises an anti-creeping device and a cylindrical shell, and the back face of the anti-creeping device is fixedly connected with the front end of a push rod. A circular push plate is arranged at the rear end of the push rod, the rear end face of the circular push plate makes contact with the front end of an airbag, and the front end face of the circular push plate makes contact with a baffle arranged in the cylindrical shell; a conical blade is arranged on the inner side of the bottom of the cylindrical shell, a compression spring is arranged outside the conical blade, the tail end of the compression spring is fixed to the inner side of the bottom of the cylindrical shell, and the front end of the compression spring is fixed to the tail end of the airbag; and a flange plate is arranged in the middle of the push rod, and a closed space is formed between the flange plate in the cylindrical shell and the baffle and is provided with aluminum skimmings. The flange plate is in clearance fit with the cylindricalshell, and the push plate is in clearance fit with the cylindrical shell. Through holes in clearance fit with the push rod are formed in the centers of the front end plate of the cylindrical shell andthe baffle. The spring is in interference fit with the tail end of the conical blade. The airbag is located on the rear portion in the cylindrical shell.
