On the Kinematic of Generalized Oldham Couplings

The purpose of this study aims at the kinematic study of generalized Oldham couplings by conducting kinematic analysis, kinematic simulation, and prototype experiment. First, the characteristics of generalized Oldham couplings are presented. Then, kinematic analysis and kinematic are performed. Finally, a prototype and its associated experimental setup are established. An experiment is conducted to evaluate the performance of the coupling. The simulated result shows that the output of the coupling is non-uniform, and close to a sinusoid. The experimental result indicates that the experimental output approximately agrees with the theoretical, but with fluctuations and a phase lag.
