The invention provides a motor train unit body front end structure adapting to composite material headstock installation. The motor train unit body front end structure comprises an annular frame, inclined wall parts, a transverse wall part, traction beams, coupler installation profiles, installation plates and a reinforcing plate. The annular frame is tightly attached to the front end of the section of the cylindrical motor train unit body and is in welded to the side walls of the motor train unit body, a roof and the outer side part of a chassis; the outer edge contour of the annular frame isconsistent with the outer contour of the motor train unit body, the annular frame is of an inclined structure, and the annular frame and the cross section of the motor train unit body are inclined connecting faces. The inclined wall parts are arranged on the left side and the right side of the front end of the motor train unit body, one ends of the two inclined wall parts are fixedly welded and connected to the annular frame, and the other ends of the two inclined wall parts are fixedly welded and connected to the transverse wall part. After the head and the tail of the motor train unit are changed into a composite material headstock structure from an original metal material headstock, the weight of the motor train unit body is reduced, and the headstock manufacturing cost is reduced. Thenovel structure at the front end of the motor train unit body can be matched with the composite material headstock for installation.
一种适应复合材料车头安装的动车组车体前端结构,所述的车体前端结构包括环型框,斜墙部件,横墙部件,牵引梁、车钩安装型材、安装板、加强板、所述的环形框紧贴筒型车体断面的前端,与车体侧墙、车顶及底架外侧部焊接连接,环形框外缘轮廓与车体外轮廓一致,环型框为倾斜结构,环型框与车体横断面呈倾斜连接面,车体前端两侧左右设有斜墙部件,两个斜墙部件的一端与环型框焊接固连,两个斜墙部件的另一端焊接固连一个横墙部件;本发明动车组首尾车车头由原金属材料车头改为复合材料车头结构后,有利于车体的轻量化,有利于降低车头制造成本。车体前端发明的新结构可实现与复合材料车头相匹配安装。
