Abstract: To solve the two problems of design parameters combination explosion and complex mapping between design parameters and imagery goals in the automotive exterior design,based on the basic idea of product gene network,the gene network model of automotive exterior was established by taking the design parameters and image target as the nodes,the correlation between the nodes as the edge.The interior association and the mapping relationship between the two sets of design parameters and image objects of automobile modeling were expressed.According to the sensitivity and degree of nodes,the nodes were classified,and the key node and node group were selected to assist designer to make decision.Based on 106 modeling parameters,the three-dimensional parametric model for 146 common type models established,and the correlation between parameters was calculated and analyzed.The image evaluation experiment was carried out for 20 image targets,and the genetic network model of automobile modeling was established by using experimental data.Based on the repeated modeling process of different samples,the existence and stability of the network model were proved by comparison.
