摘要
汽车零件薄壁化是轻量化的重要途径,本文针对薄壁化门板的加强筋结构进行分析.从加强筋形状、宽度、高度、间距几个维度对零件进行仿真分析.结果表明,采用六边形加强筋比矩形结构更稳定,具有更好的抗翘曲变形能力;加强筋宽度增大、高度增加,间距减小,这几个方案都能提升零件刚度;加强筋质量相同的情况下,相比增加加强筋的宽度、减少加强筋间距,增加加强筋的高度对改善零件刚度更加有效.
Abstract
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.
