The field of computational dynamic is surveyed, focusing on issues relevant to develop complex and numerical efficient mathematical models. Considering the topic of mathematical model, today various formalisms are available for generating dynamical modes in the form of the linear or nonlinear differential equations. In this paper we would like to represent multibody formalism, that is applied to generate equations of motion (nonlinear differential equations) for a system of rigid and flexible bodies with arbitrary topology in a symbolic form. The formalism is general and could be used for any kind of mechanical system (vehicle, human body, gearbox, etc.), with arbitrary complexity and with arbitrary degree of freedom and therefore represents general computer support to the numerical analysis, necessary for understanding and improving design process. This general proposed tool is used to handle vehicle dynamic to demonstrate the efficiency of proposed approach.
