The Bricard Linkage Network Constructed by Bennett Linkage: Design Method and Kinematic Analysis

Abstract

The paper focuses on a Bricard Linkage network constructed by Bennett Linkage and discusses the possibility of connecting Bricard linkage using Bennett linkage as the connection. To simplify the problem, accessible geometric parameters are set without much loss of generality. This new design can also evolve into some new mechanisms by connecting the linkages in different ways. Based on the designed connection idea, the corresponding three-dimensional model is created by Onshape. Using Onshape, the movement and deployment of each mechanism could be observed. Then the kinematic analysis is carried out with Adams software, to find out how the kinematic angles vary as time increases. A physical model is made to observe the deployment process more clearly, indicating a potential application of a retractable table. Since the problem has been simplified by setting accessible parameters, the mechanism may show some further performance worthy of being explored if the parameters are more complicated.
