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 %.

How to evaluate the dynamic response of tracking photovoltaic support system?

To effectively evaluate the dynamic response of tracking photovoltaic support system, it is essential to perform a tracking photovoltaic support systematic modal analysis that enables a comprehensive understanding of the inherent dynamic characteristics of the structures.

What are the dynamic characteristics of the tracking photovoltaic support system?

Through processing and analyzing the measured modal data of the tracking photovoltaic support system with Donghua software, the dynamic characteristic parameters of the tracking photovoltaic support system could be obtained, including frequencies, vibration modes and damping ratio.

Does tracking photovoltaic support system have a modal analysis?

While significant progress has been made by scholars in the exploration of wind pressure distribution, pulsation characteristics, and dynamic response of tracking photovoltaic support system, there is a notable gap in the literature when it comes to modal analysis of tracking photovoltaic support system.

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.

Does a tracking photovoltaic support system have finite element analysis?

In terms of finite element analysis, Wittwer et al., obtained modal parameters of the tracking photovoltaic support system with finite element analysis, and the results are similar to those of this study, indicating that the natural frequencies of the structure remain largely unchanged.
