| 摘 要： | 通过分析功能公差、配合公差和储备公差之间的关系,合理地确定了焦面板孔与单元配合的公差等级.提出了焦面板孔与单元配合的可靠度概念及设计方法.利用配合件尺寸服从正态分布条件的可靠度公式,定量地反映了焦面板孔与单元的实际配合达到设计要求的程度.计算结果表明,这种方法较传统设计方法更加科学,为判断焦面板孔与单元的配合设计是否合理提供了一种科学的评价方法.

| Abstract: | The tolerance grade of the focal-plane hole and unit was determined by analyzing the function tolerance,fit tolerance and conservation tolerance.The reliability concept and designing method were put forward.The coherence of the fact fit and design demand for the focal-plane hole and unit was reflected quantitatively using reliability formula of normal distribution.The results indicate that this method is more scientific than the traditional one.A scientific appraisal method for the judgement of fit reasonableness of the focal-plane hole and unit was provided. |
