Acceleration improvement for coil winders of RRRCC type by variable input speed method

This paper aims to propose a variable speed approach for minimizing the output acceleration of coil winding mechanism, and verify its feasibility by simulation. Firstly, the structure of RRCCC winding mechanism is described. Then, its kinematic dimensions are examined. Furthermore, the design approach of the variable speed trajectory is presented. Finally, the feasibility and validity of the proposed approach are investigated by Kinematic simulation. The results show that the proposed approach can effectively reduce the output acceleration; therefore the vibration and the inertial force of the shuttle can be minimized.
