Damage Risk Evaluation and Optimization for BIWS Spots-Weld

摘要

A spots damage risk evaluation method was proposed based on the spots axial and shears force. The spots damage risk index for a SUV BIW was calculated and evaluated, and the BIWs spots were optimized. The evaluation results show that most of the positions with high risk spots are the same with the damaged spots of the road or bench test. The spots damage problem was solved by optimizing the spots based on risk index. This method can achieve the spots damage risk evaluation and optimization efficiently.
