A Kind of Analysis Method of Torsion Natural Frequency for Photovoltaic Tracking Brackets Considering Anchorage Flexibility of Purlins
Aiming at the problem that the accuracy of the calculation results of the torsion natural frequency of the photovoltaic tracking bracket is not high,an analysis meth-od is proposed in this paper.The influence by the anchorage flexibility of the purlin on the overall torsion frequency of the tracking bracket is taken into account and the simulation results are verified by experiments.And then,the structural rebuilding of the tracking support in the power station is performed to improve its torsion natural frequency while the accuracy of the analysis method is verified by the field test once more.
