| Abstract: | A finite element model for the body-in-white of a home-made car is set up, with which the both strength and stiffness for static bending and torsion of all its panels are analyzed. The results of analysis are then applied to thickness optimization. The result shows that by changing the thickness of sensitive panels the strength and stiffness of the body-in-white have improved obviously. This provides a reference for the optimal design of car body. |
| Keywords: | Car body Panel thickness Sensitivity Optimization |
