Abstract

Abstract: Branch is one of the important issues in mechanism synthesis and design.Based on the concept of Joint Rotation Space (JRS),presents a simple method for the branch identification of a two-DOF seven-bar planar linkage.The JRS,branch curves,the characteristics and the formation of branches are also discussed.The branches of the two-DOF seven-bar planar linkage can be classified into two categories,which can be automatically identified with computer-aided program.Using the software of VC++,the algorithm can be implemented and the branches of the seven-bar linkage can be visualized with a simplified graphical image.All the mobility information can be easily obtained from the developed software.Hence the branch can be automatically identified.It provides a good tool for the design of two-DOF seven-bar linkages and manipulators.

Key words: mobility, branch, Joint Rotation Space (JRS), manipulator, automatic identification
