Title: Simulation and optimization of a dual-axis solar tracking mechanism
Authors: Catalin Alexandru
Affiliation: Transilvania University of Brasov
Abstract: This paper deals with the simulation and optimization based on virtual prototyping tools of a tracking mechanism used to increase the efficiency of photovoltaic (PV) systems. The proposed solar tracker is one with two degrees of freedom (so called dual-axis, or bi-axial mechanism) of the equatorial type, which is able of reproducing with great accuracy the real movements of the sun-earth astronomical system. Another advantage of such a system is that the two movements (diurnal and elevation) are independent, which allows the control process to be simplified. The actuation of the tracking system is carried out with two linear actuators, one for each of the two movements. The optimization process is approached from three points of view, each influencing in a specific way the energy efficiency of the PV tracking system, as follows: optimizing the mechanical device of the solar tracker, which intend to determine the optimal arrangement of the two actuators; optimizing the open-loop control system, which aims at optimal tuning of the control elements; optimizing the bi-axial tracking program, with the aim of maximizing the amount of incident solar radiation captured by the PV module. The study is carried out using a virtual prototyping platform that integrates, into the mechatronic concept, the commercial software packages ADAMS (for designing the mechanical device) and EASY5 (for designing the control system).
Title: The Rebound of Impact with Granular and Plastic Surface
Authors: Ahmet Faruk Akhan; Dan B Marghitu
Affiliation: Motion Capture Laboratory, Department of Mechanical Engineering Auburn University
Abstract: The study aims to investigate the normal and oblique impact of a sphere (tennis ball) on a granular surface (clay) and two different plastic tape lines.
In this research, we model the impact force with a mathematical elasto-plastic force model, and a differential approach is used. The model is applied for the impact with granular material (green clay) and plastic surfaces (line tapes). We investigated the normal and oblique impact dynamics of a sphere, a tennis ball. The impact duration is divided into two phases: compression with an elastoplastic force and restitution with an elastic force. The laboratory experiments in various configurations are recorded with a high frame-per-second camera and analyzed using image processing methods.
The mathematical model for the impact with rebounds is verified with the experimental set-up for the considered surfaces. The viscoelastic and the elastic forces agree well with the experimental data. The impact parameters are compared between the granular surface and plastic tapes. The ANOVA test suggests a robust statistical significance in the coefficient of restitution between granular surfaces and plastic tapes.
Our force model for impact performs well, and the impact response of the sphere on the granular surface and the plastic line tapes are significantly different.
