6 FAQs about [The horizontal tie rod of photovoltaic support]
Are flexible PV support structures prone to vibrations under cross winds?
For aeroelastic model tests, it can be observed that the flexible PV support structure is prone to large vibrations under cross winds. The mean vertical displacement of the flexible PV support structure increases with the wind speed and tilt angle of the PV modules.
How wind induced vibration response of flexible PV support structure?
Aeroelastic model wind tunnel tests The wind-induced vibration response of flexible PV support structure under different cases was studied by using aeroelastic model for wind tunnel test, including different tilt angles of PV modules, different initial force of cables, and different wind speeds.
Do flexible PV support structures deflection more sensitive to fluctuating wind loads?
This suggests that the deflection of the flexible PV support structure is more sensitive to fluctuating wind loads compared to the axial force. Considering the safety of flexible PV support structures, it is reasonable to use the displacement wind-vibration coefficient rather than the load wind-vibration coefficient.
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.
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.
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 %.
