Taking into account the actual purpose of the photovoltaic support, once it is unstable, it will cause serious adverse consequences to the entire system. Therefore, instability is also one of the key issues that need to be considered for photovoltaic stents. So what are the parts of the instability process of the photovoltaic support? What caused the problem? The answer will be revealed soon.
The instability process of a photovoltaic support mainly includes two stages, namely anterior buckling and posterior buckling, but the two are unified in the load-deflection curve of the electrical response from load to failure. When the photovoltaic stent is damaged by instability, its critical load is the stable ultimate bearing capacity. Therefore, the ultimate bearing capacity of the photovoltaic stent is an important limit state to be considered in the design.
With the continuous development of photovoltaic brackets in the direction of light and thin walls, the possibility of this problem will become higher and higher. Considering that the bearing capacity of the bracket depends largely on the nature of the material, the application of high-strength materials is also increasing. It is widely used to ensure the stability of the photovoltaic support through its excellent performance.
