The invention provides a cast structure hole stress determination method and a cast structure aided design method and device, and belongs to the technical field of hole stress calculation. The method for determining the hole stress of the cast structure comprises the steps that a structure model of the cast structure is built based on size data of the cast structure, and the structure model is a hollow shell structure model; determining and forming a fluid inlet and a fluid outlet on the structure model based on the pre-trepanning position of the cast structure; injecting fluid into the structure model through the fluid inlet, enabling the fluid to flow out through the fluid outlet, and obtaining a first flow rate when the fluid passes through the pre-trepanning position; forming a hole in the structure model according to the pre-forming position, injecting fluid into the structure model through the fluid inlet, enabling the fluid to flow out through the fluid outlet, and obtaining a second flow rate when the
