Embodiment Construction
[0036] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:
[0037] The calculation process of the present invention is as figure 1 As shown, in order to better understand the technical solution of the present invention, the above algorithm is applied to the common analysis of the mechanical connection between the composite material plate and the metal plate. The analysis content is: nail load distribution calculation, and stress field analysis around the maximum nail load hole . The connector is a single lapped plate with three nails, as shown in Figure 2. The following steps are based on the finite element software ANSYS:
[0038] Step 1. According to the actual length and width of different plates to be connected, establish a geometric surface at the position of the respective middle plane, move the origin of the working plane to the position of the nail, rotate the working plane, and move the plane along the X directi...
