Abstract: This paper considers single degreeoffreedom (DOF), closedloop linkages with a designated input angle and one design parameter. For a fixed value of the design parameter, a linkage has input singularities, that is, turning ...

Abstract: Cognate linkages are mechanisms that share the same motion, a property that can be useful in mechanical design. This article treats planar curve cognates, that is, planar mechanisms with rotational joints whose coupler ...

Abstract: Cognate linkages provide the useful property in mechanism design of having the same motion. This paper describes an approach for determining all coupler curve cognates for planar linkages with rotational joints. Although ...

Abstract: This paper extends the general method to construct a singularity trace for single degreeoffreedom (DOF), closedloop linkages to include prismatic along with revolute joints. The singularity trace has been introduced in the ...

Abstract: Precisionpoint synthesis problems for design of fourbar linkages have typically been formulated using two approaches. The exclusive use of pathpoints is known as “path synthesis,â€‌ whereas the use of poses, i.e., ...
