6 FAQs about [Photovoltaic support rod processing]

What are the dynamic characteristics of photovoltaic support systems?

Key findings are as follows. Dynamic characteristics of tracking photovoltaic support systems obtained through field modal testing at various inclinations, revealing three torsional modes within the 2.9–5.0 Hz frequency range, accompanied by relatively small modal damping ratios ranging from 1.07 % to 2.99 %.

What are the dynamic characteristics of the tracking photovoltaic support system?

Through processing and analyzing the measured modal data of the tracking photovoltaic support system with Donghua software, the dynamic characteristic parameters of the tracking photovoltaic support system could be obtained, including frequencies, vibration modes and damping ratio.

How many rods are in a photovoltaic axis bar?

The axis bar is composed of 11 shaft rods. Photovoltaic panels are installed on the photovoltaic support purlins. The reciprocating rotation (tilt angle) of the axis bar allows the panel to receive direct sun. The structure is symmetrical with respect to the axis bar, and the axis bar provides a fixed axis for torsional deformation.

Why is a photovoltaic support system prone to torsional vibrations?

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.

What is the modal damping ratio of a photovoltaic support system?

Additionally, consistently low modal damping ratios were measured, ranging from 1.07 % to 2.99 %. Secondly, modal analysis of the tracking photovoltaic support system was performed using ANSYS v2022 software, resulting in the determination of structural natural frequencies and mode shapes.

How stiff is a tracking photovoltaic support system?

Because the support structure of the tracking photovoltaic support system has a long extension length and the components are D-shaped hollow steel pipes, the overall stiffness of the structure was found to be low, and the first three natural frequencies were between 2.934 and 4.921.
