动车组车辆车体结构设计+文献综述
动车组车体底架作为车体的重要部分，在此我单独对车体底架进行设计建图。动车组底架设计一些牵引梁、枕梁、边梁、横梁等结构保证了动车组底架的刚度强度；同时还要在底架部位设计减振隔音的材料；运用 UG对车底架进行碰撞的有限元分析。最后完成动车组底架与车体部分的装配。

The design of emu vehicle car body structure
Abstract：This design, the overall size according to the type CRH2 emu emu vehicle body is
24500 mm length, 3380 mm wide, 3700 mm high. Using the UG software, to the emu car body
for 3 d modeling. Designed the emu side of the body, the structure of the roof and side walls,
doors and Windows, the size is the size of the reference to the emu CRH2. The bullet train to
design the streamline car body structure; At the same time to ensure that the train car body
sealing; High-speed emu and the vibration control, pressure control, noise control to improve
passenger comfort; High-speed emu need good impact resistance for improvement of the train
running safety. Car body structure of aluminum alloy material selection.
Emu vehicle chassis as the important part of the body, here I alone was carried out on the car
body chassis design built figure. The emu chassis design some traction beam, pillow beam,
beam and beam structure ensures the emu chassis rigidity strength; While in the chassis parts
design of vibration insulation materials; Using UG to collision body frame finite element
analysis. Finally completed the emu chassis and car body parts of the assembly.
Keywords：The emu；The structure of emu vehicle；The structure of emu vehicle chassis
