| Abstract: | A combination of working conditions was created, acceleration loading simulation method was used, based on the variable density method and"wrap surface" scheme, the structural topology of the battery rack of the electric logistics vehicle was optimized. The lightweight design of the bracket was carried out through size optimization to obtain a structural design solution that meets the performance and lightweight requirements. The simulation results show that the overall stiffness of the optimized battery holder is increased by 10.5%, and the total mass is reduced by 29.2%. |
