| Abstract: | The object of the study was a new type of high-speed railway passenger car body of a 250 km/h stainless steel spot welding structure. The load parameters and working conditions were determined based on standard EN12663. With the ANSYS15.0, the strength and stiffness of the car body steel structure was analyzed and calculated by finite element. The calculation results show that the calculation stress is less than the allowable stress of the material under different working conditions for the car body steel structure. The static stiffness and strength meet the requirements. The results provide a reference for the optimization design of car body and the structure improvement. |
