The Application of Moving Frame in the Calculation of Spiral Bevel Gear’s Principal Curvature

Wang Yuqing,Liang Jian

Strategic Study of CAE 2001, Volume 3, Issue 12,   Pages 68-70

Abstract:

the calculation of contacted points´ principal curvature is the key to determine contacted areaTraditionally, the method of determining principal curvature is to make use of the theory of mesh andsurface, moving frame and co-differential are employed to give a sententious, effective algorithm of principalcurvature.This algorithm can be used for calculation of principal curvature in all kinds of curve surfaces.
