 Abstract
In the paper a method for establishing and solving the movement equation in the case of the plane mechanisms is presented. The method is based on the expressing of the dynamic equilibrium in instantaneous powers of all the forces and moments that work on the component links of the mechanism. The variation of the angular speed of the driving crank is determined by numerically integration of the movement equation using the finite differences method. Finally, some simulation results in the case of a quadrilateral mechanism are shown.

 Rezumat
In articol se prezintă o metodă de stabilire şi rezolvare a ecuaţiei de mişcare în cazul mecanismelor plane. Metoda se bazează pe exprimarea echilibrului dinamic în puteri instantanee a tuturor forţelor şi momentelor care lucrează pe elementele componente ale mecanismului. Variaţia vitezei unghiulare a manivelei conducătoare se determină prin integrare numerică a ecuaţiei de mişcare folosind metoda diferenţelor finite. In final, sunt prezentate o serie de rezultate ale simulărilor în cazul unui mecanism patrulater.
