Abstract: The paper presents the first theory and practice of freeform conjugation modeling. It introduces the concept of masterslave that broadens the traditional computer aided single geometry modeling to dual geometry modeling. ...

Abstract: This paper addresses the fundamental issue on the conjugation for any gearing systems after tooth modification. It presents a rigorous theory on compensated conjugation for gear transmission error (TE) balance. The basic ...

Abstract: For finite rigid body motion, every two successive screw displacements can be represented by one equivalent screw displacement. However, such phenomenon should not be considered naturally to be valid for incompletely ...

Abstract: This paper proposes a simple and general approach for the identification of the dead center positions of singledegreeoffreedom (DOF) complex planar linkages. This approach is implemented through the first order equivalent ...

Abstract: This paper addresses the assembly strategy capable of deriving a family of overconstrained mechanisms systematically. The modular approach is proposed. It treats the topological synthesis of overconstrained mechanisms as ...

Abstract: According to Camus’ theorem, for a single degree-of-freedom (DOF) three-body system with the three instant centers staying coincident, a point embedded on a body traces a pair of conjugated curves on the other two bodies. ...

Abstract: This paper proposes a method to deal with the orientation uncertainty problem affected by joint clearances. To solve this problem, it is necessary to establish the theory of mobility of the floating link of multi-loop ...

Abstract: This paper proposes a kinematic model to evaluate the orientation uncertainty range of spherical linkages caused by the joint clearances. Based on the concepts of imaginary clearance link, spherical N-bar rotatability laws, ...
