新一代GPS的公差矢量化技术探讨

Study on Vectorial Tolerancing Technique of New Generation GPS

对新一代GPS的矢量公差技术进行探讨,提出替代要素的概念.研究了如何借助替代要素实现零件名义几何特征及变动的描述,为公差设计技术研究奠定理论基础.

The vectorial tolerancing technique of the new generation GPS is discussed.The concept of substitute feature is introduced at first.Then how to describe the nominal geometrical features and the variations of these features by means of substitute features is studied.It establishes theoretical basis for the study of tolerance design technique.
