The wind-induced vibration characteristics of the photovoltaic support system are investigated from a time-domain analysis perspective, offering valuable insights for the wind resistance design of array photovoltaic tracking supports.
What can be shown by the modal test results and finite element simulations of the tracking photovoltaic power generation bracket tracking photovoltaic support system was that the natural vibration frequency of the structure has a slight increase as the inclination angle increases.
Due to the lower natural frequencies and torsional stiffness, the system is susceptible to significant torsional vibrations induced by wind. Currently, most existing literature on tracking photovoltaic support systems mainly focuses on wind tunnel experiments and numerical simulations regarding wind pressure and pulsation characteristics.
Analyzing the aerodynamic loads on both solar panels and their support structures is crucial in the operation of a PV system. However, there is limited research on the wind-induced response of flexible cable-supported photovoltaic systems, with a notable lack of quantitative assessment of wind vibration responses.
