The invention discloses a modeling method for the rapid generation of pilot holes in a skin part. The method comprises the following steps of (1) selecting the coordinates of the central points of hole positions in a model structure tree; (2) selecting the plane of to-be-opened holes in a model geometry, and selecting the input aperture of a user interface; (3) selecting the geometry information of all to-be-opened holes in the model structure tree, and opening all to-be-opened holes at one time. According to the technical scheme of the invention, the coordinates of the central points of hole positions in the model structure tree are selected, and then the information including the plane of to-be-opened holes, the input aperture of the user interface, and the geometry information of all to-be-opened holes in the model structure tree, are selected. After that, all to-be-opened holes are opened at one time, so that the position accuracy of pilot holes is ensured. Meanwhile, the workload of designers is reduced and the working efficiency is improved.
Description
technical field [0001] The invention relates to a modeling method, in particular to a modeling method for rapidly generating guide holes in skin parts. Background technique [0002] Skin parts are the panel parts and the foreskin of the internal structural framework that make up the aerodynamic shape of the aircraft. After the skin is subjected to aerodynamic action, the force is transmitted to the connected fuselage and wing frame. The force is complex, and the skin is in direct contact with the outside world. Therefore, not only the skin material is required to have high strength and good plasticity, but also a smooth surface. It has high corrosion resistance. At present, most of the skin parts produced are single-curvature or double-curvature skin parts, and the accuracy requirements for modeling various structural elements during the forming process are also high. Guide holes are one of the typical structures. element. [0003] During the processing and manufacturing ...
