On one way to build up a computer model of the multibody system dynamics

A technology of an object-oriented modeling is under consideration. This technology is applied to the cases of the multibody systems virtual prototypes dynamics creating. General approach for creating the models is described. The approach is based on the multiport representation for the mechanical system to be simulated. The object-oriented paradigm turned out to be an efficient tool for constructing complicated models especially for the cases of large or very large dimencions. Several examples of the machines dynamical models from different topics were implemented.
