| Abstract: | In order to study whether the crashworthiness of a tractor-trailer car in China meets the national safety standards,side crash simulation analysis was carried out.Firstly,the finite element model of the car and the moving barrier is established,and the parameters of material,property and contact are defined.Then LS-DYNA is imported to solve the problem,and the result parameters of the output node are obtained.Finally,the safety standard of the car side crash is obtained by referring to the relevant safety regulations of car side crash. |
