In this paper, the calculation formulas of high-order derivatives based on wavelet scaling function and their associated derivative product integrals in the Galerkin finite element method are given, so that the wavelet Galerkin method can be used to solve higher-order derivatives The numerical calculation of boundary value problems of differential equations makes it possible to solve structural mechanics problems. Numerical examples show that this method has good calculation accuracy.
