| 摘 要： | 目前，白车身制造误差的诊断方法存在抽检频率低、样本量小及耗时长等问题。文章提出利用变形云图分析法来实现白车身制造误差的误差源诊断。综合有限元分析理论、黄金分割法和主方向法，以车门制造误差为分析对象，诊断出夹具变形为误差源。结果表明，此方法可用于装焊夹具的误差诊断，其结论在虚拟试验中得到验证。但有限元法在白车身误差分析中的应用是全新的研究课题，实用价值有待在生产环节中做进一步验证。

| Abstract: | Low sampling frequency,small amount of sample and long time-consuming existed in the diagnosis method of body in white manufacturing error.Use deforming cloud analysis method to achieve error sources diagnostic of body in white manufacturing.Combined with finite element analysis,theory of 0.618 method and main direction method,taking the door as the analysis object,fixture deformation as the error sources was found out.The results indicate that this method can be used on weld and assembly fixture error sour... |
