摘　　要：为了提高木制轨道玩具的品质和设计效率,基于有限元理论和编程语言,研究木制轨道玩具结构性能评估和数字化设计技术。首先通过Femap+NX Nastran软件有限元仿真,对其连接结构性能进行分析并提出一种优化模型。进而开发基于OpenGL的木制轨道玩具导轨轮廓线的辅助设计软件,并利用Solid Edge软件的开发技术设计了木制轨道玩具的参数化设计原型系统,从而实现了集CAD与CAE于一体的木制轨道玩具数字化设计。To improve the quality and design efficiency of wooden rail toys,the structural performance assessment of wooden toys and digitalized design technology were studied based on finite element method and programming language. Firstly,through Femap+ NX Nastran finite element simulation,the research analyzed wooden rail toys’ structural performance and put forward an optimization model. Then auxiliary software of wooden rail toys’ guide rail contour line based on Open GL was developed. Besides,by utilizing Solid Edge’s development technology,a parameter design prototype system for wooden rail toys was designed. Thus,realizing the digitalized design of wooden rail toys,which integrates CAD and CAE in one.
