The Galerkin Method

For the fan structure, 8-node isoparametric quadrilateral elements are used to discretize the structure based on the fan blade shape while 20-node isoparametric hexahedron elements are used to discretize the surrounding air of the fan blade. The intensity of pressure at an arbitrary point in the surrounding air can be solved by the Galerkin method when the boundary condition is considered. The Wilson-Θ method with good stability is used to solve the air-structure coupling equations. The calculated natural modes and the tested natural modes are compared. The mode method is used to calculate and analyze the fan blade dynamic characteristics in order to study the air-structure coupling.
