Analysis of complex mechanical systems based on the block diagrams and the matrix hybrid graphs method

In the article a new method of an analysis of three-dimensional, complex mechanical systems with linear couplings, structurally and geometrically heterogeneous and subjected to polar and flow sets of functions at the same time has been introduced. The method is connected with a matrix hybrid graph (mhg)-of combined features of both flow and polar – being transformed into the matrix block diagram. That graphs are isomorphic with the structure of a discrete model of the mentioned mechanical system.
