公差分析是预测几何变化对产品质量影响的关键工具。在过去的几十年里，人们提出了各种计算机辅助公差分析方法，每种方法都有其特定的优点和缺点。本文结合典型案例，定量比较了三种公差分析方法，即公差堆栈、矢量回路和基于小位移变形量的公差分析方法与基于皮肤模型形状的公差分析方法。该贡献的新颖之处在于对这些方法及其结果的深刻评估。
Tolerance analysis is a key tool to predict the consequences of geometric variations on product quality. During the last decades, various approaches for the computer-aided tolerance analysis have been proposed, where each of them has specific advantages and disadvantages. In this contribution, three tolerance analysis approaches, namely tolerance stacks, vector loops, and the tolerance analysis based on the Small Displacement Torsor are quantitatively compared with the tolerance analysis based on Skin Model Shapes considering a typical case study. The novelty of the contribution lies in the profound assessment of these approaches and their results.
