Linkage Mechanism Design Based on Primary Cell Classification and Engineering Semantics

A kinematic chain portion composed of two linkages and three lower pairs are taken as primary cell and classified into different schemes.A comprehensive classification of linkage mechanism concerning the composition of primary cells,the pattern of motion driving,and the way of fixing to stationary frame is established with the corresponding semantic description.This approach accelerates the process of designing a new linkage scheme to match the required path curve,and the schematic diagram can be readily converted to a 3D configuration of the mechanism by mapping the linkages and joints to detailed parts chosen from a customized CAD library.
