Abstract The cardioid crank is a planetary mechanism that generates line. It with varying length and speed moves along the used to replace of rocker mechanism, its approximate uniform motion obtained. kinematic analysis method studied in this paper. calculating for limit position oscillating angle time ratio guide bar are given. Finally, conditions synthesis put forward accordance or oscillate ...

The mechanical linkage of a hydraulic-resistance, elbow flexion and extension exercise machine was redesigned to provide a resistance response that varies in proportion to female joint strength over the range of motion. The aim was to integrate into a simple, passive exercise machine the respective benefits of hydraulic resistance and isokinetic exercise. Hydraulic resistance facilitates bidire...

This paper summarizes the work done in context of an industrial research project collaboration between Italian Institute Technology and company Fameccanica Data Spa. introduces design a six bar linkage mechanism, actuated by single motor, for re-orienting aligning objects. The main application consists grasping empty bottles lying flat on input conveyor, rotating, placing them upright position ...

Six-bar linkages have been used in some prosthetic knees in the past years, but only a few publications have been written on the special functions of the mechanism as used in transfemoral prosthesis. This paper investigates the advantages of the mechanism as used in the prosthetic knee from the kinematic and dynamic points of view. Computer simulation and an experimental method were used in the...
