A Study on the Characteristics and Modeling Method of the Spot Welding Interface for Car Body Panal |
| |
| Abstract: | Four types of elements are respectively applied to model a spot welded structure for car body in this paper. The strengths and weaknesses of each model are discussed based on the comparison between numerical solution and the result of experimental modal analysis. A new method for modeling a car body with large numbers of welded spots is proposed and the static and dynamic results both show good agreement with the tests. |
