A novel dimensional synthesis technique for solving the mixed exact and approximate motion synthesis problem for spatial CC kinematic chains is presented. The methodology uses an analytic representation of the spatial CC dyad’s rigid body constraint equation in combination with an algebraic geometry formulation of the perpendicular screw bisector to yield designs that exactly reach the prescrib...

The evolution of requirements for mechanical products toward higher performances, coupled with never ending demands for shorter product design cycle, has intensified the need for exploring new architectures and better design methodologies in order to search the optimal solutions in a larger design space including those with greater complexity which are usually not addressed by available design ...

This paper proposes algorithms for mechanism synthesis and analysis, including Rotation, Center, Connection, Numeric Differentiation, Animation and Index. These algorithms are used to transfer behaviors into structures, and to transfer structures into kinematic and dynamic behaviors of the structures. The algorithms are valid for the synthesis and analysis of different mechnisms. These algorith...

Abstract. When implementing the technological process on crank presses, it is necessary to provide a predetermined working cycle of slider motion: fast lifting, dwell, and slow lowering. The cannot be realized without controlling motor. In addition, using controllable motors increases manufacturing cost. Due geometric kinematic capabilities mechanism, changing kinematics link best choice. Thank...

We describe a framework for robust kinematic design based on tolerance analysis and parametric design via configuration space manipulation. The input is a parametric model of a planar mechanical system comprised of lower and higher kinematic pairs in open or closed loops. The robust synthesis task is to find a nominal design that functions correctly despite small parameter variations. This task...
