摘　　要：为探究光伏玻璃的抗冲击性能,得到其在不同工况下的裂纹扩展模式和破坏的冲击力。基于建立的有限元模型,研究不同冲击高度和不同光伏玻璃厚度对最大冲击力等指标的影响规律。结果表明:不同的冲击形式导致的玻璃裂纹形态不同,风致飞射物的冲击高度越低或玻璃板的厚度越大,玻璃的破坏程度越小,抗冲击性能越好,安全性越高。2 m下落高度时的落锤冲击力为5.46 kN,相比0.5 m下落高度时的冲击力提高1.17倍;12 mm厚的光伏玻璃板破坏时所需要的冲击力为20.75 kN,相比3 mm厚光伏玻璃板所需要的冲击力提高9.07倍。In order to study the impact resistance performance of photovoltaic glass,the crack growth mode and the peak impact force under different working conditions were proposed.Based on the established finite element model,the influence law of different impact heights and thicknesses of photovoltaic glass on the maximum impact force and other indicators was studied.The results showed that the crack shape of glass caused by different impact forms was different.The lower the impact height of wind⁃induced projectiles,or the larger the glass plate thickness,the smaller the damage degree,the better the impact resistance and the higher the safety of the glass.The impact force of the falling hammer at a height of 2 m is 5.46 kN,which is 1.17 times higher than the impact force at a height of 0.5 m;The impact force required for the destruction of a 12 mm thick photovoltaic glass panel is 20.75 kN,which is 9.07 times higher than the impact force required for a 3 mm thick photovoltaic glass panel.
