TY - JOUR PY - 2011// TI - Multi-disciplinary optimisation for front auto body based on multiple optimisation methods JO - International journal of vehicle design A1 - Gao, Yunkai A1 - Sun, Fang SP - 178 EP - 195 VL - 57 IS - 2/3 N2 - In order to improve the performance of the front autobody, multiple optimisation methods are adopted in different stages. Firstly, topology optimisation is made under the combination of multiple load cases. Secondly, size optimisation is done for the original design under multiple load cases. After these two optimisations, the first optimisation stage is completed. Then, based on the first modification, crashworthiness optimisation is carried out by using Kriging surrogate model, which means the second stage optimisation. The final results derived after two stage modifications indicate that combining multiple optimisation methods and balancing each target are effective to realise multi-disciplinary optimisation. Keywords: multi-disciplinary optimisation; topology optimisation; surrogate models; vehicle design; modelling; crashworthiness.
