Abstract
In this article, a new method of calculating mobility for planar kinematic chains, based on kinematic graph of mechanism and matrix theory, is put forward. We proposed a new conception of network graph of mechanism to describe kinematic chains instead of kinematic graph of mechanism. With a network graph of mechanism, the displacements of components produced by applied forces can be calculated effectively and simply. Futhermore, matrixes can be established by displacement and force equation groups. By means of analyzing the matrixes, we will obtain the mobility of a mechanism with no efforts as the mobility equals to the dimension of the matrix arrived at from equation groups. In addition, this new method is applied to various kinds of mechanisms in plane efficiently and correctly including the kinematic chains with passive constraints and common constraints. The method of this paper can be extended to calculate mobility of spatial mechanisms too.
