| Abstract: | Aiming at a side-crash improvement problem of a sedan, the paper uses a method that combines orthogonal ex- perimental and finite element simulation to turn it to a optimum problem of 7 factors and 2 levels. Then 8 optimum cases are calculated. Based on extremum difference analysis,the most effective component on side-crash erashworthiness is found. Finally,a optimization is performed and the simulation results indicate that the optimization with cost enhances side-crash crashworthiness greatly. |
