Structural optimization of automotive thin-walled door panels
The design of thin-walled automotive parts is an important way to reduce their weights.This article analyzes the reinforcing rib structure of thin-walled door panels.Simulation analysis was conducted on the parts from the dimen-sions of reinforcement rib shape,width,height,and spacing.The results indicated that compared to a rectangular struc-ture,the use of hexagonal reinforcement ribs was more stable,and it generated a better resistance to warping deforma-tion.Increasing the width,height of the reinforcement ribs and reducing their spacing can all enhance the stiffness of the part;when the mass of the reinforcement ribs is the same,compared with increasing the width and reducing the spacing of the reinforcement ribs,increasing the height of the reinforcement ribs is more effective in improving the stiffness of the part.
