| Abstract: | Using CRH3 EMU as a carrier,the crash simulation is carried with PAM-CRASH software.Through analysis the deformation,energy absorption,force,impact time,velocity and acceleration of the CRH3 EMU are obtained.By adding dummy model and numerical simulation,the damage index of the dummy mode is evaluated,and a key factor in causing bodily harm is proposed.Thus,passive safety of the vehicle is implemented,and a theoretical basis is provided to the enterprise. |
