Application of Computer 3D Modeling Technology in Graphic Image Design

Abstract

In order to solve the problem that the manual input data work efficiency is low and the optimization cannot be achieved in the section modulus calculation, the author proposes a computer-aided 3D graphic design method for ship hull structure. First, complete the modeling of the ship hull, complete the statistical calculation of the size in the CAD platform, solve the static moment, and complete the three-dimensional modeling; Calculate the inertial load and wave load of the ship during work, and calculate the wave bending moment, and substitute it into the three-dimensional model for verification. Finally, according to the computer-aided three-dimensional graphic design process, the specification verification of the ship’s scale is completed, the graphic file is associated with the database, and the three-dimensional graphic design is completed. Experimental results show that the maximum stress of the original three-dimensional integrated graphic design of the ship is 202 MPa, and the maximum deformation is 87.352 mm. Based on the computer-aided three-dimensional integrated graphic design of the ship, the maximum stress is 226 MPa, and the maximum deformation is 76.234 mm. In conclusion: the hull obtained by the computer-aided three-dimensional graphic design of the ship can effectively reduce the total area and materials of the midsection structure of the ship, reduce the weight of the hull, and realize the optimal configuration of the midsection material of the ship.
