This paper studies on the stress analysis over large-size automobile frame joints. The frame consists of some cross members and two side members. In this case, joints of the frame have a large effect on the automobile motions. So, to study on the contact between the members and the rivets is very important. In order to obtain the more similar real model, the used model in this paper was designed with shell elements and modeled by considering the spring effects. As a result of this study, we can obtain the relations between the cross member anjxthickness and maximum principal stress, also obtain the correlation between the rivets and the maximum principal.
