Abstract：A new type of front-end energy-absorbing structure for metro vehicles was introduced.The mature energy-absorbing components and the combined energy-absorbing structure were modularized,and the dynamic collision simulation was carried out by using the finite element software,the impact shape of the front-end energy-absorbing structure was simulated,the process of energy-absorbing was analyzed,and the values of vehicle impact interface force,vehicle body deformation and energy-absorbing were calculated.Finally,the deformation and energy-absorbing stability of the front-end energy-absorbing structure of vehicles were verified by the test.The test and simulation results match and can meet the requirements of the vehicle collision standard.
