Analysis and Research on the Crashworthiness of Intercity Electric Multiple Units
With the increasing speed of rail trains,the passive safety of trains is increasingly emphasized.Taking a certain type of intercity electric multiple unit as the research object,this paper carries out a detailed simulation analysis of the different collision scenarios of the train by using Hypermesh and Ls-Dyna finite element simulation software,obtains key parameters such as the speed,deformation and energy change of the train during collision,and verifies the crashworthiness of the train from the aspects of passenger living space,longitudinal average deceleration,wheel lifting,etc.,which can provide case references and theoretical basis for the anti-collision design of similar trains in the future.
