Imitation Study of Hybrid-driven Five-bar Mechanism Output Movement Characteristic Based on Kinematics Analysis

摘要

Hybrid-driven five-bar mechanism that combines the motions of two characteristically different motors can attain the flexibility output movement.Its structure is simply and it has low cost.Therefore it is widely used manufacture fields.In this paper,the kinematics mathematic model of plane closed-loop five-bar mechanism is established according to the model-transforming method and closing-vector method.And expressions of its output movement parameters are attained.The output movement characteristic of hybrid-driven five-bar mechanism is imitated and studied.The results show that hybrid-driven five-bar mechanism which its geometry parameters confirmed can accomplish diversiform tasks through changing its input movement rule.Output movement track of hybrid-driven five-bar mechanism changes along with the original position of two input components changing.It indicates hybrid-driven five-bar mechanism can accomplish many group tasks at one time.
