摘要
本文采用概率方法,根据广义尺寸链中终结环与各组成环之间的非线性函数关系,在已知组成环功能参数的误差分布的条件下,导出终结环功能参数的数字特征、分布形态、基本规格以及偏差的计算方法。并探讨了该方法与统计公差之间的联系。
By probability method and non-linear functional relation between end ring and all constituent ones in generalized dimensional chain, a method is derived for calculating numerical characteristics, distribution form, basic specifications and deviation of functional parameters in end ring with known error distribution of that in constituent ones, and relation between the method and statistic tolerance also approached.
