First create a simple beam model of finite element simulation analysis, find the principle and method of equivalent ACM solder joints, then the equivalent method of ACM welds a car white body finite element model is established, by using NASTRAN analysis modal, torsional rigidity and bending rigidity, and compared with the experiment on the mark, has the very good correlation. The results show that based on the 5mm×5mm mesh size, the equivalent ACM solder joint model is reasonable and reliable for the modal and static stiffness modeling analysis of BIW.
