The article reveals main simulation concepts implemented in EULER, a software product for automated analysis of multi-component mechanical systems. Formal representation of a mechanical system and general principles of forming and solving motion equations are shown. Dynamical equations for the flexible bodies undergoing small deformations and moving as parts of a mechanical system are derived. Finite-element method, Craig-Bampton matrixes reduction method, and more general approach than the ones known from the literature are used to derive the equations.
Keywords: mechanical system, constraints equations, flexible body, finite-element method, Craig-Bambton method.
Mots-clés : motion equations
