全柔性化CAD系统在系列产品结构设计中的应用研究

Research on Full Flexible CAD System in Series Product Structure Design

介绍了T-FLEX CAD全柔性化的特点,以共享单车产品系列化为例,首先基于人体工程学推算出自行车结构模块中关联零部件间的尺寸关系,根据确定参数关系数据表来建立柔性的零部件模型库。针对不同需求,选择和修改模型库中的目标参数,快速生成目标产品的二维工程图和三维造型。最后通过ANSYS的应力分析进行材料的选择以及结构参数合理性的检验,完成产品的设计。仿真结果表明该系统有助于在产品系列化中提高设计效率。

This paper describes the characteristics of T-FLEX CAD full flexibility.Taking the shared bicycle product seriation as an example,firstly,the size relationship among the related components within bicycle structural modules was calculated based on ergonomics.Then a flexible component model library was established,according to the confirmed parameter relationship data sheet.Furthermore,focusing on different demands,by selecting and adjusting the target parameters in the model library,the two-dimensional（2D）engineering drawing and 3D model of the target product would be rapidly generated.Finally,the material selection and the verification of structure parameter rationality would be carried out via ANSYS stress analysis,hence the design of the product was finished.The simulation result indicats that the system is helpful to improve design efficiency in the process of product seriation.
