摘　　要：为了解决三维实体结构虚拟设计中结构的奇异性问题,引进了一种结构优化近似模型,并形成了一种三维实体结构虚拟设计方法.然后,给出了几种典型工程结构和机械结构的虚拟设计实例.设计实例说明了该方法的有效性.最后,介绍了研制的结构虚拟设计软件系统-I型(SVDS I)的基本功能、发展和应用前景.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.
