The invention discloses a parameterization design method for a whole vehicle wheel trim flanging structure and a wheel trim structure, and belongs to the technical field of automobiles. The parameterization design method specifically comprises the following steps that S1, the profile step difference f1 of a wheel trim and a side wall outer plate is set; s2, setting a profile step difference f2 of the wheel trim and the vehicle door outer plate; and S3, (d1-d2 > f1 + f2) serves as an input condition, the width parameter of the front and rear segment wheel trim transition molded surface is selected, d1 is the width of the wheel trim plane A1D, and d2 is the width of the wheel trim plane A2D. Through the calibration method provided by the invention, the selection of structural parameters meeting the requirements of the precision at different sections of the wheel brow can be completed, and the target of precision control is achieved.
本发明公开了一种整车轮眉翻边结构参数化设计方法及轮眉结构,属于汽车技术领域,具体包括如下步骤:S1、设置轮眉与侧围外板型面阶差f1;S2、设置轮眉与车门外板型面阶差f2;S3、以(d1‑d2>|f1|+|f2|)作为输入条件,选取前后段轮眉过渡型面的宽度参数,其中,d1为轮眉平面A1D的宽度,d2为轮眉平面A2D的宽度。通过本发明的标定方法,可完成满足轮眉不同分段处精良性需求的结构参数的选取,实现精良性控制目标。
