Abstract: 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.

Abstract: The purpose of this study aims at performing the kinematic study of the coil winder with a RCRC mechanism by investigating the geometry and conducting kinematic simulation. First, the motion principle of the shuttle is addressed. Then, the topological structure of the RCRC mechanism is examined, and its kinematic chain and kinematic sketch are drawn. Finally, a design example of the RCRC mechanism is given for illustration, and its feasibility is verified by performing kinematic simulation using ADAMS software. Finally, the simulated result shows that the shuttle can produce the required winding motion.

Abstract: The objective of this paper aims at investigating the feasibility of new coil winders with a spatial RSPC mechanism by conducting kinematic simulation. First, the design requirements and design constraints are specified based on the kinematics characteristic of coil winders. Then, the (4, 4) kinematic chains are obtained by number synthesis, and the atlas of feasible chains is generated. After that, the atlas of specialized feasible chains is found. Finally, new designs are obtained through the particularization process. In addition, an illustrated example of the RSPC mechanismselected from the new designs is given, and its feasibility is verified by performing kinematic simulation using ADAMS software. The result shows that it can meet the motion requirement of coil winders.

Abstract: The purpose of this study is to present a novel concept for inline vibrating conveyors, and verify its feasibility by kinematic simulation. First, new conveyor is presented, and its merits are discussed. Then, its kinematically equivalent linkage is described. Moreover, the kinematic dimensions are investigated from its geometry. Finally, the solid model for the proposed design is established, then kinematic simulation is performed by ADAMS software. The simulation results indicate that the proposed new design can effectively advance the workpiece.
