Disclosed is a standard motor train unit power bogie frame. The standard motor train unit power bogie frame is characterized in that side beams and a beam are connected in splicing and variable section mode, an upper cover plate of each side beam extends inwards, and achieves variable section butting against an upper cover plate of the beam through a connection block, the connection block is of a space curved face structure, a lower cover plate of each side beam extends inwards, and butts against a lower cover plate of the beam, and an outer stand plate and an inner stand plate of the beam respectively extend outward, and are inserted into the side beams and directly connected with inner stand plates of the side beams. Section variation of the standard motor train unit power bogie frame can not cause stress concentration and achieves comparable stress level. The connection block is of the space curved face structure, and achieves smooth transition from the upper cover plates of the side beams to the upper cover plate of the beam on geometrical characteristics, and therefore smooth transmission of stress between the upper cover plates of the side beams and the upper cover plate of the beam is achieved. Continuous transition of a box-like structure can be achieved, and rigidity value of the major structure of the standard motor train unit power bogie frame is at the mean value level, and then a rigidity increase on a connection area and stress concentration caused by the rigidity increase are avoided.
