Design of Movable Bracket for Dual-Axis Tracking Solar Thermal Power System

Movable bracket as an important part of dual-axis tracking solar thermal power system is large, movable and complex of its force with the orbit of connected nodes. At the same time, the system has strict requirements on removable bracket’s deformation. The technical feasibility and the cost lever of the bracket structure play decisive roles in the promotion of the application of this new type of solar thermal power system. This paper clarifies the applications operation of solar power system on the basis of the principle of the performance of the support structure for the system requirements, summarizes the mechanical characteristics of the bracket structure, combined with the analysis of the pilot project support structure selection, expounds the key points of structural selection, and determines a more reasonable form of the support structure.
