Design of a Dual-axis Solar Tracking Mechanism

Marc finite element analysis softwareIn this study, we aimed to design and simulate a cost-effective and structurally simple dualaxis solar tracking mechanism.A crucial aspect of the research was to ensure the system's robustness against strong typhoons and earthquakes.The initial phase involved using SolidWorks Computer-Aided Design (CAD) software to perform operational interference checks.Each part was designed at a 1:1 scale, followed by 3D solid modeling and assembly simulations to verify the proper functioning of all components within the system.Static structural analysis was conducted using MSC.Marc finite element analysis software.The analysis mode was set to elastic-plastic, with selected materials being aluminum and steel, characterized by their density, Young's modulus, and Poisson's ratio.Boundary conditions fixed the displacement at the base plate and foundation bolt holes, while load conditions included wind pressure from a Category 17 typhoon and gravitational acceleration from a magnitude 5 earthquake.Upon the completion of the design, detailed manufacturing drawings were created using AutoCAD.These drawings included precise annotations of component dimensions and tolerances, ensuring accuracy during the fabrication process.This comprehensive approach ensures that the dual-axis solar tracking mechanism is both efficient and resilient under severe environmental conditions.
