MOBILITY AND CHARACTERISTICS CHART OF 4R1P-TYPE FIVE-BAR PLANAR PARALLEL MECHANISMS

Abstract

Abstract: By introducing the concept of virtual link, the mobility of the 4R1P-type planar parallel chain/mechanisms is analyzed based on the Grashof theorem. The slide reachable range is divided into several characteristically different regions and the closed chain/mechanisms are categorized into three classes and further several sub-classes. The characteristics charts for different classes are given based on which the mobility is got according to the active/passive prismatic joint, the slide position, and the real structure of the links. The presented method is helpful to all the 4R1P-type mechanisms and 3R-type open chain mechanisms.

Key words: 4R1P-type five-bar parallel mechanisms, Active prismatic joinf, Characteristics chart, Mobility, Passive, prismatic joint
