Method for optimizing laying track of laying belt of each layer of composite material laminated plate with holes

The invention relates to a method for optimizing the laying track of each layer of laying belt of a composite laminated plate with an opening, which comprises the following steps of: constructing a local coordinate system by taking the center of the opening in the composite laminated plate as an original point, and defining the laying track of each layer of laying belt of the composite laminated plate based on an ideal fluid cylinder streaming streamline cluster; the number of layers of laying belts cut off by opening holes can be reduced, the damage degree of a force transmission route is reduced, an overall coordinate system is established with the opening hole center in the composite material laminated plate as the original point, and the number of layers of laying belts corresponding to the composite material laminated plate is changed through coordinate transformation. Finally, the corresponding laying belt laying angle of each finite element grid of the geometric model of the composite material laminate
