| Abstract: | Calculation methods of car-body strength in domestic and international standards are analyzed. A new developed domestic rail car body is taken as the example to research the generated method of car-body finite element model and the calculation method of car-body strength,and to put forward a project method of car-body strength evaluation in order to offer the theory guarantee for the construction design and strength analysis of the high-speed car body, then the structure of rail car body is optimized according to the calculation result so as to ensure the maximum axle load of the rail car meet the design requirement. |
