Abstract
Research on non-twist criterion of rope is the theoretical basis of the application of rope in engineering field. Aiming at the twist problem of ropes between two relative rotation platforms, this paper introduces a kind of avoiding twist mechanism and calculates its transmission ratio of the epicyclic gear train. Based on the twist model and mathematical description of rope, a non-twist criterion is analyzed and proposed. Then, this paper reveals that how the revolving speed ratio acts on rope twist by using the method of anti-rotation and non-twist criterion. Furthermore, the avoiding twist mechanism is extended to the case of three rotation platforms and its kinematic relation for avoiding twist is analyzed. Finally, the application of avoiding twist mechanism on optical imaging of rotation platforms is analyzed.
