摘 要: 采用NURBS表达高副约束中的曲线曲面,在此基础上研究了高到约束运动变换矩阵的结构和计算方法,所导出的公式具有通用的结构形式和规范自动的计算性质,该组公式可应用于带曲线曲面高副约束的组合机构运动学分析以及计算机辅助曲线曲面约束的装配设计。 Based on the foundation of adopting NURBS toexpress curves and curved surfaces in higher-pair constraintthis paper studied the structure and calculation method oftransformation matrix for higher-pair constrained motion. Theformulae being derived possess general forms of structure Andproperties of standard and outomatic calculation. This set offormulae can be applied to the kinematic analysis of combinedmechanism with higher-pair constraint of curves and curvedsurfaces and also the computer aided assembly design withconstraint of curves and curved surfaces.
