An exact method for analysis of kinematics for mechanisms by using vectors which form closed polygons

Abstract

Construction machinery equipments are complex, with a high degree of mobility. Their operation is done with groups of hydraulic cylinders equal in number with the mobility. This paper presents an exact calculation, which does not require large computing resources for the kinematics of these mechanisms. Relationships presented can be applied to any mechanism operated by hydraulic cylinders, whatever their mode of installation. Based on these relationships can be developed mathematical models to analyze the dynamics of machines or to make softwares for their control.
