| Abstract: | A entity model of an European city railway vehicle is imported to HyperWorks software of Altair,in HyperMesh module,the finite element crash model of a city railway vehicle is set up,and the crash simulation is carried out in LS-DYNA software.By contrast analysis of the simulation results of the optimized structure,the new structural design is acquired and a reasonable vehicle design is validated. |
