FINITE ELEMENT MODELING OF SPOT-WELDING IN DYNAMIC SIMULATION OF AUTOMOBILES

Abstract

Abstract: The simulation of spot-welding structure remains to be a critical problem when building the finite element model of an automobile body. A new technology of simulation of spot-welding is presented. The spot-welding is treated as a rigid beam element, which can treat the normal force and shear force. As a penalty, the node-coupling method is introduced to compute the forces of spot-welding nodes. When spot-welding node force meets the failure criterion, nodes of the weld are separated from each other, and the rigid beam is removed from the calculation.

Key words: Dynamic simulation, Finite element model, Spot-welding, Approximation , Feature extraction , Machining feature, Reconstruction, Reverse engineering , Tread pattern
