| Abstract: | In order to overcome the structural singularity problem in the optimization process of a complex three-dimensional continuum structure, an approximate optimal model is introduced, and a three-dimensional structural virtual design method is proposed. Then, several examples of typical and complex three-dimensional continuum structures are given. It is demonstrated that the proposed method is very effective in generating virtual designs of complex three-dimensional engineering and mechanical structures. Finally, the basic functions of the I-type structural virtual design software system that has been developed in this paper, its future development trend, and application prospects are introduced. |
