Photovoltaic support manipulator production

Can a tracking photovoltaic support system reduce wind-induced vibration?

Finite element analysis also showed a slight increase in natural frequencies with increasing inclination angle, which was in good agreement. This suggests that the design of the tracking photovoltaic support system can be optimized to reduce the impact of wind-induced vibration on the tracking photovoltaic support system.

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 inclination increase the vibration frequency of a tracking photovoltaic support system?

What can be shown by the modal test results and finite element simulations of the tracking photovoltaic power generation bracket tracking photovoltaic support system was that the natural vibration frequency of the structure has a slight increase as the inclination angle increases.

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 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 %.

Can photovoltaic support systems track wind pressure and pulsation?

Currently, most existing literature on tracking photovoltaic support systems mainly focuses on wind tunnel experiments and numerical simulations regarding wind pressure and pulsation characteristics. There is limited research that utilizes field modal testing to obtain dynamic characteristics.
