A kinematic diagram or kinematic scheme illustrates the connectivity of links and joints of a mechanism or machine rather than the dimensions or shape of the parts. Often links are presented as geometric objects, such as lines, triangles or squares, that support schematic versions of the joints of the mechanism or machine.〔J. J. Uicker, G. R. Pennock, and J. E. Shigley, 2003, Theory of Machines and Mechanisms, Oxford University Press, New York.〕 A kinematic diagram is sometimes called a joint map or a skeleton diagram. For example, the figures show the kinematic diagrams (i) of the slider-crank that forms a piston and crank-shaft in an engine, and (ii) of the first three joints for a PUMA manipulator. |- style="text-align:center;" | || |- style="text-align:center;" | PUMA robot || and its kinematic diagram ==Linkage graph== A kinematic diagram can be formulated as a graph by representing the links of the mechanism as vertices and the joints as edges of the graph. This version of the kinematic diagram has proven effective in enumerating kinematic structures in the process of machine design.〔Lung-Wen Tsai, 2001, ( Mechanism design: enumeration of kinematic structures according to function ), CRC Press〕 An important consideration in this design process is the degree of freedom of the system of links and joints, which is be determined using the Chebychev–Grübler–Kutzbach criterion. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kinematic diagram」の詳細全文を読む スポンサード リンク
