6 FAQs about [Force calculation of photovoltaic flexible bracket]
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.
What is a flexible PV mounting structure?
Flexible PV Mounting Structure Geometric Model The constructed flexible PV support model consists of six spans, each with a span of 2 m. The spans are connected by struts, with the support cables having a height of 4.75 m, directly supporting the PV panels. The wind-resistant cables are 4 m high and are connected to the lower ends of the struts.
What is the wind vibration coefficient of flexible PV support structure?
The wind vibration coefficients in different zones under the wind pressure or wind suction are mostly between 2.0 and 2.15. Compared with the experimental results, the current Chinese national standards are relatively conservative in the equivalent static wind loads of flexible PV support structure. 1. Introduction
How safe are flexible PV brackets under extreme operating conditions?
Safety Analysis under Extreme Operating Conditions For flexible PV brackets, the allowable deflection value adopted in current engineering practice is 1/100 of the span length . To ensure the safety of PV modules under extreme static conditions, a detailed analysis of a series of extreme scenarios will be conducted.
Do flexible PV support structures have resonant frequencies?
Modal analysis reveals that the flexible PV support structures do not experience resonant frequencies that could amplify oscillations. The analysis also provides insights into the mode shapes of these structures. An analysis of the wind-induced vibration responses of the flexible PV support structures was conducted.
Is a flexible PV support structure subjected to wind suction?
Fig. 13, Fig. 14, Fig. 15 show the flexible PV support structure is subjected to wind suction (β = 180°), the curves for the mean wind pressure coefficient in the span of S1 and S2 when the tilt angle α is 10°, 20° and 30°, respectively.
