| Abstract: | To optimize the structure of a subway middle car and shorten the design cycle, a finite element analysis model of car body is built. According to the standard EN 12663 2010, the stress distribution of the finite element model is calculated in the main cases, and the simulation result is compared with the test data. The simulation results of most of the points are very close to the test data and the most errors are within 10%. It shows that the model for calculation is reliable. At the same time, a few points with large error are located and the causes are analyzed. |
