Photovoltaic tracking bracket load calculation

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.

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.

Does a tracking photovoltaic support system respond to wind-induced loads?

Recent research indicates that the dynamic characteristics of tracking photovoltaic support system, namely inertia, damping, and stiffness, significantly influence the tracking photovoltaic support system's ability to respond to wind-induced loads, affecting its stability, reliability, and overall performance , .

What is the damping ratio of a tracking photovoltaic support system?

Moreover, the measured damping ratios associated with each mode was low, amounting to no more than 3.0 %. Table 1. The measured natural frequency and damping ratio of a tracking photovoltaic support system at different tilt angles (Frequency /H z; Damping ratio /%). Fig. 5.

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.
