Large span truss photovoltaic support

What is a large-span flexible PV support structure?

Proposed equivalent static wind loads of large-span flexible PV support structure. Flexible photovoltaic (PV) support structure offers benefits such as low construction costs, large span length, high clearance, and high adaptability to complex terrains.

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.

What is the mean vertical displacement of a flexible PV support structure?

The mean vertical displacement Zv of the flexible PV support structure at α = 10°, with wind direction angles β = 0° and β = 180°, along with varying wind speeds, are shown in Fig. 20, Fig. 21. The mean vertical displacement of both the side and mid spans increases with increasing wind speed.

What is the shielding effect of a flexible PV support structure?

While in the middle span, as α increases 10° to 20° and then to 30°, the shielding effect increases from 13.9 % to 59.8 % and then to 89.1 %. For aeroelastic model tests, it can be observed that the flexible PV support structure is prone to large vibrations under cross winds.

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 cables reduce vibration?

Liu et al. , designed a 33 m-span flexible PV support aeroelastic model and conducted wind tunnel tests to verify the effectiveness of three types of stabilizing cables in reducing vibrations in the support structure.
