| Abstract: | 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. |
