Design and Dynamic Analysis of a 2 Dual Axes Solar Tracking Mechanism

This paper describes the implementation of general multibody system dynamics on sun tracker mechanism. In this study, a dual axes solar tracking mechanism designed within the scope of a project to obtain an efficient electrical energy from solar rays is examined. Dynamic and kinematic calculations of the moving and joint places in the mechanism were made. This study is important as the use of an efficient solar tracker is very useful in military, industrial and residential areas. Free Body Diagrams of all the elements or limbs that make up the sun tracker mechanism have been drawn. Thus, dynamic and kinematic values at elements points were calculated. The proposed dynamics model of the mechanism offers an accurate and fast method to analyze the dynamics of the mechanism knowing that there is no suchwork available for sun tracker. Also, 3D tracker elements were drawn and planned in Solid Work program. The simulation gives a clear idea about energy parameters for different link lengths of the mechanism over a linear displacement.
