汽车制动器三维参数化的设计技术分析

针对传统汽车零部件设计方法的局限性，提出了基于“软原型”的设计分析方法。通过开发一套专用的CAD系统——鼓式制动器设计分析系统，深入研究了“虚拟产品”设计方法和参数化建模技术，并在软件的开发过程中，提出了一些新的解决手段。该系统基于VB语言，将数据库、图形库与设计模块结合在一起，以特征参数的获取为表征对象，利用参数驱动建模，实现了设计与分析过程的有效衔接，极大地提高了汽车制动器设计效率，缩短了产品的开发周期。

Brake 3D Models Parameterized Design

Aiming toovercome thelimitation of the traditional design methods of automobile parts, this paper presents a design and analysis method based on "Soft Prototype". By developing a professional CAD system Drum Brake Design and Analysis System, the authors researched the design method of "Virtual Products" and the technologies of parameterized modeling. During the development of software, some new methods are presented. In this CAD system, the database, graphical browser and designing module are united perfectly, and parameters are utilized to create models. Such a system can greatly improve design efficiency and reduce the time of new products development
