摘要：
Solar tracking systems and heliostats often rely on serial mechanisms with one or two motorized axes. In this paper we propose a parallel kinematic machine of type U-2PUS optimized to have a large workspace able to follow the sun's apparent motion during the year. Some issues such as singularity avoidance and link/joint collisions are included inside a constrained optimization procedure to synthesize a mechanism able to operate at latitudes among 0 degrees and 50 degrees. Design considerations and vibration analysis are also discussed in the paper. Finally, an energy assessment, to evaluate system performances with respect to other solutions based on fixed solar panels, is provided. (C) 2014 Elsevier Ltd. All rights reserved.
