摘要

LIFTGATE INNER CASTING DESIGN Stiffness The stiffness or rigidity of a liftgate structure is key to the vehicle's functionality · Resists aerodynamic wind loading and induced boom (low frequency vibration) · Resists bending and torsional static displacements · Survive abusive slam conditions without changes to system performance During design process, CAE tools (topology and free size optimizations) were used to: · Identify local ribbing · Integrated gusset · Thickness addition opportunities · Satisfy NVH and stiffness targets with minimum mass increase
