| 摘 要： | 把上偏差小于下偏差的公差定义为虚公差，探讨了虚公差存在的理论基础及其意义，从而丰富了公差的内涵而发展为广义公差，更适合计算机辅助公差设计。提出了基于虚公差的装配尺寸链计算方法。

| Abstract: | It is the first time to define the tolerance with upper deviation smaller than lower deviation as virtual tolerance which is given in this paper as well. Based on the concept of virtual tolerance, dimension chains of different assembly will simplify the analysis and calculation of fixing dimension chain which has compensator in probabilistic method, so that it is possible to calculate this sort of fixing dimension chain by probabilistic method. |
