| 摘 要： | 为了分析尺寸链中组成环公差对封闭环公差的影响程度，在公差分析过程中引入稳健设计理论，提出尺寸合格率灵敏度和产品合格率灵敏度概念．采用灵敏度公差分析方法开发出相应的计算软件，定量分析了组成环公差对封闭环公差的影响程度，通过计算得知，尺寸合格率灵敏度较小的组成环公差对封闭环公差的影响较小，产品合格率灵敏度较小的尺寸链稳健性较好。

| Abstract: | To analyze the effect of tolerance of composing loop on the tolerance of close loop, the theory of robust design is introduced in the tolerance analysis and the concepts of sensitivity of eligible probability of dimension and sensitivity of eligible probability of product are put forward. The software of calculation is developed by the method of sensitivity tolerance analysis. The effect of tolerance of composing loop on tolerance of close loop is analyzed quantitatively. The conclusion is that the effect of tolerance of composing loop on the tolerance of close loop is less if the sensitivity of dimension yield is less and the robustness of dimension chain is better if the sensitivity of product yield is less by calculation. |
