CLASSICAL AND MODERN KINEMATIC ANALYSIS APPLIED FOR MECHANISM STUDY

Abstract

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.
