The finite element analysis software ANSYS was applied to calculate the stress distribution and deformation of the car body. The riding quality, safety, stability depend on the design of the car body. It means that the strength of the car body structure must be enough to prevent the yielding, buckling, and rupture. The design principle of the car body of EMU was introduced briefly. The model of car body was constructed using the SolidWorks software. And then the ANSYS software was employed to analyze the stress and displacement for the conditions of the dead load and full load. It was found that the present design of the car body could ensure the demand of the safety factor of 1.5. The stress and deformation are all distributed at the allowance range for the dead load and full load. Keywords : Electric Multiple Units, Finite Element Method, Stress Analysis.
