摘　　要：参数化设计技术已成为产品设计过程中一种最重要的设计方法。按照所对应的对象,参数化设计分为零件级参数化设计和产品级参数化设计,零件级参数化设计技术已在生产实践中得到成功的应用,但还不便于实现产品级参数化设计,而目前的设计过程却要求实现整个产品的三维参数化。为此,基于UG软件研究了产品级三维参数化设计技术,提出了利用UG/WAVE技术来实现单个模块内部的形状关联和尺寸关联,利用部件间表达式建模技术来实现不同模块之间的尺寸关联,从而实现整个产品级的三维参数化建模。最后以机车底架为应用实例,证明了该方法简便实用,能显著提高设计效率。Parametric design technique has become one of the most important design method in the process of product design. Parametric design is divided into part-level parametric design and product-level parametric design in accordance with the corresponding objects, part-level parametric design technique has been put in practice successfully, but not easy to achieve product-level parametric design, and the current design process is required to achieve product-level three-dimensional parameter design. So, the product-level 3D parametric design technique based on UG software is studied in this paper. It puts forward the ideas of making use of UG / WAVE technology to achieve the shape and size association within a single module and making use of interpart expression modeling technology to achieve the size association between different modules, and these make it possible to achieve the entire product-level 3D parametric modeling. Finally, an application example of locomotive underframe is given to demonstrate that this method is simple and practical and can significantly improve the efficiency of design.
