The application of structural adhesive can effectively improve the structural performance of body-in-white， reasonably arrange and optimize structural adhesive， improve body-in-white performance， reduce and reduce thin steel plate， replace solder joint and so on。 In this paper， taking the performance improvement and lightweight as the optimization goal， the structural adhesive layout analysis method of CAE topology optimization is used to optimize the structural adhesive design。 Thus， the key area of performance is identified and the structural adhesive is arranged here， and finally the stiffness of body-in-white is improved。 In this paper， combined with the performance requirements of a certain vehicle model， the structural adhesive length of the body-in-white is optimized and analyzed， and the reasonable structural adhesive length suitable for a certain vehicle model is confirmed。 Finally， the torsional stiffness of body-in-white is improved by 1384 Nm/deg， fatigue problems are solved in 6 places， and the collision performance is improved; at the same time， the weight of body-in-white is reduced by about 3。95 kg。
