Abstract
Through hyperworks and Lsdyna, the side impact simulation of the vehicle model with Q&P980 class B-pilla is carried out. The middle part of B-pillar is the main part to bear the impact load, which corresponds to the occupant's chest and abdomen. The invasive displacement and the speed are large and the change trend is basically the same. After the optimization of the B-pillar weld solder joint layout, the number of solder joints was reduced by 23.61%, the structural static stiffness and the first-order torsional frequency were improved, the collision performance remained basically unchanged, and the body assembly cost was reduced.
