ROCKER MECHANISM FROM CLASSICAL TO MODERN KINEMATICAL ANALYSIS

Abstract

Kinematical mechanism analysis is usually used for motion study or to simulate and analyse the movement of mechanical assemblies and the whole mechanism. In this paper we will consider kinematical analysis regarding the rocker mechanism which is commonly used in a cross planer machine tool 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 linear velocities and acceleration, angular speeds and acceleration. The calculations were performed using graphic-analytical methods and computational method using SolidWorks Motion Analysis software which provides a special module for quick analysis with a visual representation of characteristic data mechanism for different members position as a diagram representation of certain parameters throughout the researched motion cycle, which are only some of the possible areas of analysis. The resulted calculations are presented as numerical values and chart plots for comparison and validation.
