What are the anti-resonance measures for photovoltaic bracket nuts?

1. Adding dampers: In the photovoltaic bracket system, special dampers can be added to eliminate or reduce the vibration of nuts. Damper has the function of absorbing vibration energy and can effectively suppress vibration phenomenon.

2. Optimize the structural design: By optimizing the structural design of the photovoltaic bracket and reducing the stiffness and quality of the bracket, the occurrence of * * * vibration frequency can be reduced. For example, measures such as increasing the flexible connection parts of the bracket and reducing the length of the cantilever are taken.

3. Adjust the fastening force of the nut: properly adjusting the fastening force of the nut can change the natural frequency of the bracket system, thus avoiding the vibration phenomenon. According to the situation, we can increase or decrease the fastening force of nuts through experiments, and find a suitable fastening force to reduce the risk of vibration.
