Research on Engine Hood Deformation

The hood dimension deformation is a common issue that engineers will encounter in the hood design and manufacturing process, especially after the high temperature baking in the paint shop. How to solve this issue in the early stage and to avoid additional cost because of the late change？ There is no mature method to solve before. In this paper, through comparison the simulation results and numerous test measurement data, the hood deformation CAE simulation model has been optimized, and the primary factors that influence deformation have been defined. The new method has been used in the new project, and is proved to be an effective way to solve hood deformation issue.
