公差分析中的统计公差方法综述

公差分析是公差设计中的重要问题,公差分析方法分为极值法和统计公差方法两类,其中大多数方法是以概率统计原理为基础的统计公差方法。本文介绍了常用的公差分析方法,包括极值法、方和根法、修正的方和根法、蒙特卡洛模拟法、田口试验法和卷积方法等,并对这些方法进行了比较,阐述了统计公差方法的适用性。

Review of Statistical Tolerancing Methods in Tolerance Analysis

Tolerance analysis is an important problem in tolerance design.The methods of tolerance analysis can be divided into two kinds: worst case and statistical tolerancing,and most of the methods are statistical tolerancing methods which are based upon principles of probability and statistics.The paper introduce firstly tolerance analysis methods in common use,which include Worst Case,Root Sum Squared,Modified Root Sum Squared,Monte Carlo Simulation,Taguchi Test Method,Convolution Method and so on,then it carried on the analysis and comparison to these methods,and finally it expounds an applicability of each statistical tolerancing method.
