[0002] Solar photovoltaic power generation, as a clean energy source, has experienced rapid growth in recent years. Photovoltaic mounting brackets are key components supporting photovoltaic modules in photovoltaic power generation systems. However, in practical applications, photovoltaic mounting brackets are often threatened by natural disasters such as earthquakes. When subjected to the acceleration excitation caused by random earthquakes, photovoltaic mounting brackets can generate strong horizontal lateral vibrations. This not only causes the tilt adjustment angle of the photovoltaic module platform to change, thereby reducing the energy conversion efficiency of the photovoltaic device, but also seriously affects the stability and safety of the photovoltaic modules. Therefore, it is necessary to design photovoltaic module brackets to reduce vibration and improve the dynamic stability of the photovoltaic system.
