Then, new topological models of multiple joint and geared (cam) kinematic chains, which are derived from the topological model of simple joint kinematic chains, are presented the characteristics of the new topological graphs and their associations with the topological graph of simple joint kinematic chains are also addressed. This paper presents a simple method, based on the concept of contracted graphs, for the enumeration of basic kinematic chains with simple and multiple joints. The research on the enumeration of basic kinematic chains started in the mid-sixties  using graph theory and group theory concepts and it is still of mayor importance because the available automated tools to design mechanisms are limited by the size of the kinematic chain. Kinematic enumeration is the process of determining all possible kinematic chains or mechanisms satisfying certain predetermined criteria there are elegant mathematical methods for the enumeration of kinematic chains (such as graph theory).
1 introduction the most important phase in the design of a mechanism is to find the most adequate topology for a certain task this phase is called the structural synthesis of kinematic chains or enumeration of kinematic chains. A problem still unsolved in kinematics is the enumeration of a complete list of kinematic chains and mechanisms without isomorphisms and without degenerate chains that operate in any screw system in this paper, a method for the enumeration of kinematic chains without isomorphisms and degenerate . 8 enumeration of kinematic chains and mechanisms the dictionary meaning of enumeration is to list one by one to count kinematic enumeration is the.
Mechanism design: enumeration of kinematic structures according to function introduces a methodology for systematic creation and classification of mechanisms with a partly analytical and partly algorithmic approach, the author uses graph theory, combinatorial analysis, and computer algorithms to create kinematic structures of the same nature . Proceedings of the 1st international and 16th national conference on machines and mechanisms (inacomm2013), iit roorkee, india, dec 18-20 2013 loop based algorithm for automatic sketching of planar kinematic chains. Eﬃcient enumeration and hierarchical classiﬁcation of planar simple-jointed kinematic chains: application to 12- and 14-bar single degree-of-freedom chains. 18 enumeration of kinematic chains and mechanisms the dictionary meaning of enumeration is to list one by one to count kinematic enumeration is the process of determining all possible kinematic chains or mechanisms satisfying certain predetermined criteria. Enumeration of optimal pin-jointed bistable compliant mechanisms with non-crossing members have been developed for enumerating the basic kinematic chains with .
The enumeration process can be achieved either by storing various kind of numerous kinematic chain and mechanisms in the memory or by completely generating them for given problem however the most. In this paper the author used graph theory and combinatorial analysis for enumeration of graphs of kinematic chains contracted graphs with up to four loops and six verti. The original theoretical aspects presented in this thesis are: (i) the development of a new identifier of isomorphism of mechanisms and its use in the enumeration of kinematic chains and different atlases of mechanisms. Enumeration, kinematic, static and mechanical efficiency analysis of differential screw mechanisms. 25 enumeration of kinematic chains and mechanisms: 25 enumeration of kinematic chains and mechanisms 26 spherical and two-dimensional space.
A problem still unsolved in kinematics is the enumeration of a complete list of kinematic chains and mechanisms without isomorphisms and without degenerate chains that operate in any screw system . Further applications of group theory to the enumeration and structural analysis of basic kinematic chains. A kinematic chain, in which one link is fixed or stationary, is called a mechanism, and a linkage designed to be stationary is called a structure contents 1 uses.
In 1985  gave a method to select the input and output links in distinct mechanisms under the study of structures analysis and syntheses of kinematic chains and mechanisms the given equation is in a convenient form for the application of the least square methods.

Traditionally, mechanisms are created by designer's intuition, ingenuity, and experience however, such an ad hoc approach cannot ensure the identification of all possible design alternatives, nor does it necessarily lead to optimum design mechanism design: enumeration of kinematic structures . During the enumeration of kinematic chains there are some chance of enumerate duplicate kinematic chain because a lack of reliable mechanisms of a kinematic chain .
