摘要： 为提高汽车尾灯装配效率，提出基于影响系数矩阵范数的尾灯区域稳健设计方法.建立了尾灯区域螺纹联接偏差和尾灯面观测点位移变化关系的数学模型，提出用影响系数矩阵的行向量1范数、条件数和逆矩阵范数这3个目标函数来评价装配偏差敏感度.以某车型尾灯区域为例，通过有限元仿真得到数学模型数值解，并进行尾灯板结构稳健设计.与实际装配调整过程的一致性表明了数学模型的准确度.

Abstract: In order to improve the efficiency of automobile taillight assembly, a method of robust design based on norms of influence coefficient matrix was employed in taillight area. A model of the mathematical relation between the deviations of screw joints and observation points in taillight area was established. Three objective functions, namely, 1norm of row vectors, condition number and norm of the inverse matrix of the influence coefficient matrix, were used to evaluate the sensitivity of the deviation to assembly structure. Taking the taillight area of some car as an example, finite element simulation was used to obtain the numerical solution of the mathematical model, then the assemble structure was optimized. Quality problems of the production site verify the predictive accuracy of the mathematical model.
