Photovoltaic module glass breaking failure simulation method

The invention discloses a photovoltaic module glass breaking failure simulation method. The method comprises the following steps: obtaining material characteristic parameters of photovoltaic glass and an interlayer adhesive film through a test; establishing a basic model by using LS-DYNA display dynamics software according to the size of the photovoltaic module and the requirements of an impact test ice hockey; defining a photovoltaic module supporting boundary condition and an ice hockey impact speed according to a standard impact test requirement; respectively defining material attributes of the photovoltaic module according to the material parameters; and judging the failure condition of the photovoltaic module according to the LS-DYNA calculation result, and determining whether the standard specification is met or not. The method can be used for predicting the bearing capacity, the failure mode and the crack propagation of the glass under different working conditions, provides a basis for the optimization
