Representation of planar kinematic chains with multiple joints based on a modified graph and isomorphism identification [PDF]

Mechanism and Machine Theory, 2022
The representation and isomorphism identification of kinematic chains (KCs) with multiple joints are crucial issues to be solved in mechanism research. In this paper, a modified graph—planar face graph (PF graph), is proposed.

Isomorphism Identification of Graphs of Kinematic Chains

Volume 8: 31st Mechanisms and Robotics Conference, Parts A and B, 2007
Isomorphism identification of graphs is one of the most important and challenging problems in the fields of mathematics, computer science and mechanisms. This paper attempts to solve the problem by finding a unique representation of graphs. First, the perimeter loop of a graph is identified from all the loops of the graph obtained through a new ...

Logical Foundations of Kinematic Chains: Graphs, Line Graphs, and Hypergraphs

Journal of Mechanical Design, 1990
In terms of concepts from the theory of graphs and hypergraphs we formulate a precise structural characterization of a kinematic chain. To do this, we require the operations of line graph, intersection graph, and hypergraph duality. Using these we develop simple algorithms for constructing the unique graph G (KC) of a kinematic chain KC and (given an ...

An Innovative Approach to Detect Isomorphism in Planar and Geared Kinematic Chains Using Graph Theory [PDF]

Journal of Mechanical Design, Transactions of the ASME, 2017
Detection of isomorphism in planar and geared kinematic chains (GKCs) is an interesting area since many years. Enumeration of planar and geared kinematic chains becomes easy only when isomorphism problem is resolved effectively. Many researchers proposed

Variation, Kinematics and Further Graphs

1979
Variation in mathematics is the study of the interdependence of variables. For instance, in the formula obtained for simple interest in chapter 2 (volume 1) $$I = \frac{{PRT}}{{100}}$$ the interest ‘varies’ as the principal P, the rate R and the time T. If any one of these quantities changes, then the interest changes.

Exoskeleton systems kinematics analysis with graph-matroid approach

2011 IEEE International Conference on Automation Science and Engineering, 2011
This paper presents a novel technique for the kinematic analysis of exoskeleton systems, based on incidence matrices in an edge-oriented graph. Kinematic equations are generated in matrix form using a base of circuits from a cycle matroid. This set of independent equations, automatically generated due to matrix orthogonalities, allows efficient ...
