A nail load calculation method considering nail hole contact and nail bending

The invention provides a nail load calculation method considering nail hole contact and nail bending, which can be used in the fields of aerospace and mechanical design and manufacture. At present, the main methods to determine the nailing load are test measurement and finite element method used for carrying out nail load calculation. The former takes a long time and requires a lot of preparatorywork and equipment, while the latter requires more hardware, and contact analysis requires more grid, which is difficult to converge and consume a long time, so it is often difficult to be realized inpractical engineering. In order to solve the shortcomings of the prior art, the invention provides a nail load calculation method considering the contact characteristics of the nail hole and the nailbending. On the basis of fully utilizing the existing two-dimensional model solution, the nail load calculation method considering the contact characteristics of nail hole and the bending of connecting nail is realized by intr
