Abstract: The subject of Bresse's circles is classical in the kinematics of planar mechanisms. These are the loci of the coupler points that exhibit either zero normal or zero tangential acceleration. Described in this paper is the ...

Abstract: The present paper deals with the formulation of novel closedform algorithms for the kinematic synthesis of quasiconstant transmission ratio planar fourbar and slider–crank linkages. The algorithms are specific for both ...

Abstract: This article deals with the synthesis and analysis of Stephenson III six-bar motion generators with, a coupler link instantaneous stop of the five-bar loop and a crank-driven four-bar loop. The proposed design procedure ...

Abstract: Understanding the geometry of gears with skew axes is a highly demanding task, which can be eased by invoking Study's Principle of Transference. By means of this principle, spherical geometry can be readily ported into its ...

Abstract: As the coupler link of an RCCC linkage moves, its instant screw axis (ISA) sweeps a ruled surface on the fixed link; by the same token, the ISA describes on the coupler link itself a corresponding ruled surface. These two ...

Abstract: Camus' concept of auxiliary surface (AS) is extended to the case of involute gears with skew axes. In the case at hand, we show that the AS is an orthogonal helicoid whose axis (a) lies in the cylindroid and (b) is normal ...

Abstract: The subject of this paper is the kinematic synthesis of volumetric rotary machines, also known as GeRotors (GEnerated ROTORs), which are based on the planetary motion of suitable regular curvepolygons. In particular, the ...

Abstract: The kinematic analysis of the planar motion of vehicles, such as common cars, buses, and trucks, when traveling along linear and circular tractrices at low speeds, is proposed here based on the fundamentals of the kinematics ...
