Mechanism kinematic analysis is usually used for motion study or for simulating and analyzing the movement of mechanical assemblies and the whole mechanism. In this paper we will consider kinematical analysis regarding the simplest crank mechanism without taking into account forces that cause the mechanism motion. The authors have used a calculation model and a calculation algorithm that allowed the definition of kinematic parameters of the mechanism, including crank displacements, angular velocities and acceleration, angular speeds and acceleration. All calculations were performed using a few grapho-analytical classical application methods and the Mathcad mathematical package. The results of the calculations are reported as numerical values and graphic presentations.
Analiza cinematică este, de regulă, utilizată pentru studiul mișcării sau pentru simularea și analizarea mișcării ansamblurilor mecanice sau a întregului mecanism. În această lucrare analiza cinematică este aplicată mecanismului simplu, fără a lua în considerare forţele care determină mișcarea mecanismului integru. A fost aplicat un model de calcul și un algoritm care permite definirea parametrilor cinematici ai mecanismului, incluzând deplasările manivelei, vitezele unghiulare și acceleraţia. Toate calculele au fost efectuate folosind metode grafo-analitice clasice și software Mathcad. Rezultatele calculelor sunt raportate în formă de valori numerice și grafice.
