【Abstract】 Problems encountered in the design of the statistical dimensional tolerance, such as the conversion of statistical parameters of distribution, the quantitative calculation of the tolerance of the statistical component link and statistical closing link, and the finding of a simple design method in consistence with distribution requirements, are discussed. Such methods as multiple convolution, discrete approximation, etc. are presented. These methods are suitable for a design to be performed on a computer and partially for quick design in practice.The work reported is part of a preliminary investigation in connection with the preparation of Chinese standards on the statistical tolerance.更多还原
