Abstract: The analysis of mechanical efficiency constitutes an important phase in the design analysis of gear drives. The objective of this investigation has been the development of a general algorithm ...

Abstract: It is well known that the circulating power in gear trains can be many times greater than the input power. Such circumstances require that in the design of split-power gear drives, a preliminary ...

Abstract: Briefly recalling some of the latest procedures of kinematic analysis that technical literature records, a numerical method is proposed for approximate calculus of angular velocities and accelerations ...

Abstract: A numerical finite differences algorithm, given by a first differentiation formula and that can be used for repeated differentiations, has been deduced on the basis of an approximation technique ...

Abstract: Although differential screw mechanisms are widely used in precision mechanisms to control fine relative movements, their enumeration and systematic methods of analysis seem less widespread. In ...

Abstract: The formulation of the dynamic equations of motion proposed by Udwadia-Kalaba is discussed from the point of view of numerical efficiency. Since this formulation requires the computation of a pseudoinverse matrix, it has ...

Abstract: This paper presents the analysis and design of a robotic worktable with a structure based on two platforms connected by three four-bar linkages. The worktable has three rotational degrees-of-freedom ...
