在公差和偏差模拟中，灵敏度分析用于评估公差规格和几何偏差对装配关键特性的影响，支持产品和工艺开发人员得出更合适的公差决策，并优化制造和装配工艺。然而，已有的在变化模拟背景下进行灵敏度分析的方法忽略了在考虑形状偏差时发生的重要的统计相关性。为了克服这些缺点，提出了一种基于皮肤模型形状的基于密度的灵敏度分析方法，用于考虑形状偏差的变化模拟。结合一个典型的公差分析案例，对该方法进行了重点讨论。
In tolerance and variation simulations, sensitivity analyses are used to assess the influences of tolerance specifications and geometrical deviations on the assembly key characteristics and to support product and process developers in deriving more suitable tolerancing decisions and in optimizing manufacturing and assembly processes. However, established methods to the sensitivity analysis in the context of variation simulations disregard important statistical dependencies, which occur when considering form deviations. To overcome these shortcomings, an approach to the density-based sensitivity analysis in variation simulations considering form deviations based on Skin Model Shapes is presented. The method is highlighted and discussed employing a typical tolerance analysis case study.
