| Abstract: | HyperMesh and LS-DYNA are applied to make a simulation analysis of the crashworthiness of several thin-walled rail with variable sections.The impacts of variable sections on load variation and energy absorption are studied.The sole section of the thin-walled rail and energy absorption characteristics of mixed thin-walled rail with variable section are compared and analyzed.The results show that mixed thin-walled rail with variable section is more in line with the ideal vehicle crash performance compared wit... |
