| Abstract: |
| According to the structure feature of aluminium-alloy car body and engineering requirement, based on the method, that including genetic algorithm studied cross section, conformation and topological optimization, this paper discussed the optimization model, optimization conformation of section and topological optimization of rib distribution. The application software, had been compiled and a case study was completed. Design variables covered 70％ of load carrying structure, it conforms the validity of the method. |
