Abstract:

A rib equivalence model was proposed based on the equavalence theory of the bas element stiffness. Through a contrast analysis between the equivalence model and the traditional detailed model, the accuracy of the equivalence model was improved. A group of experiments was designed and performed to validate the equivalence model. The result provides a reference for the improving the accuracy and the effectiveness of CAE in the car body concept disign phase.

Key words: vehicle engineering, car body, rib equivalence model, stiffness equivalence theory, CAE
