| Abstract: | In this paper, the passive safety and crash performance of New Delhi RMGL project car body in AW3 condition is studied using finite element software HyperMesh and Ls-Dyna. Tile model which is a train crashing another train using spring instead of coupler is established. The crash process of two trains is analysed using instantaneous non-linear finite element crash simulation method. The result proves that the safety design of this vehicle meets tile requirements of EN 15227. |
