4 FAQs about Stepless speed change of photovoltaic bracket
Do flexible PV support structures amplify oscillations?
The research explores the critical wind speeds relative to varying spans and prestress levels within the system. 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.
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 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.
Do large-span flexible PV supports fail at critical wind speeds?
Li and his team studied the instability mechanisms and failure criteria of large-span flexible PV supports, concluding that triangular and cross diagonal braces fail at critical wind speeds of 51 m/s and 46 m/s, respectively.
