Abstract: The conditions for the existence of extreme velocity ratios in spherical four-link mechanisms have been investigated by algebraic means. It is shown that, in the general case, all such extreme ...

Abstract: Velocity fluctuations in skew four-bar mechanisms with a simple skew (that is, skew four-bar mechanisms in which the planes of the crank circles intersect the common perpendicular between the ...

Abstract: Algebraic conditions have been derived for determining the complete or partial rotatability of the input and output links of a class of five-link, R-C-R-C-R, spatial mechanisms with zero offset ...

Abstract: Using Cayley’s construction of parallelograms and similar triangles, the existence of the coupler cognate of the geared five-link mechanism is established for the general case in which the coupler ...

Abstract: Using (3 × 3) matrices with dual-number elements, closed form displacement relationships are derived for a spatial five-link R-R-C-C-R mechanism. The input-output closed form displacement ...

Abstract: Using the principle of similarly varying triangles, the existence of the coupler cognate of space five-link RHHHH and HHRHH mechanisms is established for the general case in which the coupler ...

Abstract: The necessary conditions for the existence of two-loop six-link R-R-C-C-R-C-C overconstrained mechanism are developed by extending Dimentberg’s approach of passive coupling. The developed conditions ...

Abstract: Dimentberg’s approach of passive coupling is extended to develop necessary and sufficient conditions for the existence of five-link spatial mechanisms with helical, cylinder, revolute, and prism ...
