Energy Absorption Configuration of Crashworthy Metro Train
In this paper,a simulation method based on joining non-linear finite element and multi body dynamics is developed to solve the energy configuration of crashworthy metro train.The relationships of non-linear springs which describe characters of forces-deformation for energy absorption during crash event are obtained by using non-linear Finite Element Analysis (FEA) techniques.Then they are used in simulation for collision of two metro train sets with multi-body dynamics.Compare to the different energy absorption configuration,the results of impact force,deformation,velocity and acceleration are analyzed to assess the passive safety of whole train set.The results indicate that the joining simulation strategy is feasible and effective.It can be used to improve the metro train crashworthiness design by optimizing the energy absorption configuration.
