The invention provides a freight motor train unit body structure which comprises a roof, a bottom frame, end walls and side walls, the bottom frame comprises a floor and side beams, and the freight motor train unit body structure is characterized in that the side walls are partitioned side walls, each partitioned side wall is formed by fixedly connecting longitudinal aluminum profiles and aluminumprofile door stand columns, and a large-opening-degree door opening is formed between the two partitioned side walls; a door upper reinforcing beam is welded between the upper side of the door standcolumn and the roof boundary beam, the side wall door stand column, the door upper reinforcing beam and the underframe boundary beam jointly form a doorway frame type structure, and a door lower reinforcing beam is fixedly connected to the lower portion of the underframe boundary beam in the corresponding area of the vehicle door. The large-opening-degree doorway structure guarantees the strengthof a vehicle body and the modal requirements of the vehicle body through the doorway frame type structure and the door lower stiffening beam.

    本发明提供一种货运动车组车体结构,包括车顶、底架、端墙、侧墙,所述底架包括地板和边梁,其特征在于:所述侧墙为分块侧墙,所述分块侧墙由纵向铝型材和铝型材门立柱固定连接而成,两个分块侧墙间设置大开度门口,在门立柱上侧和车顶边梁之间焊接门上补强梁,所述侧墙门立柱、门上补强梁与底架边梁共同形成门口框架式结构,车门对应区域的底架边梁下方固定连接门下加强梁。大开度门口结构通过所述门口框架式结构和门下加强梁保证车体强度和车体模态要求。
