6 FAQs about [Flexible support photovoltaic module vibration]
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.
Are cable-supported PV modules prone to vibrations under wind excitation?
However, because the cable-supported PV modules also possess high flexibility and low damping, they are prone to large vibrations under wind excitation. In the present study, a series of wind tunnel tests were conducted to simulate the wind-induced vibration (WIV) of a type of cable-supported PV modules.
What is flexible PV module support structure?
Under the circumstance, the span of the fixed PV supports is too small, which leads to the innovative use of flexible PV module support structure. The concept of flexible PV support structure was first introduced by Baumgartner [7, 8, 9] in which the PV panels were supported by cables (see Figure 1).
What is wind-induced vibration in flexible PV support systems?
Wind-induced vibration (WIV) in cable-supported systems plays a critical role in determining structural safety , . Research related to wind-induced vibration in flexible PV support systems is still relatively limited.
Are flexible PV support structures prone to vibrations under cross winds?
