基于参数化技术的鼓式制动器设计系统的开发研究
摘要
制动器是汽车上的关键部件。随着汽车工业的飞速发展以及人们生活水平的普遍提
高,对汽车制动器的设计提出了更为严格的要求。不仅要满足制动器基本性能的要求,还
要满足环保的严格要求。因此,改进制动器的设计方法具有重要的现实意义。本文主要对
鼓式制动器的参数化设计、UG 的二次开发等问题进行了研究。
首先,论述了CAD 技术在国内外的研究现状及发展过程,对制动器的发展历程进行了
回顾。确定了以基于特征的参数化方法进行鼓式制动器设计系统的开发研究工作。在确定
了离散化原则的基础上,对各种结构型式的鼓式制动器进行了科学的离散化处理。选择具
有典型特征的制动器总成和单个零部件进行了三维参数化建模工作,建立了参数化模型库
以备调用。
其次,采用 VC++作为编译环境,利用 UG 二次开发工具完成参数化窗口的设计、菜单
的设计、回调函数以及 UG 模型文件管理系统的编码设计。
最后,运用编程语言完成了鼓式制动器辅助设计模块的设计。

RESEARCH AND DEVELOPMENT ON THE DESIGN SYSTEM
OF DRUN BRAKE BASED ON PARAMETERISM
TECHNIQUE
ABSTRACT
Automotive brake is the ponent of auto. With the rapid development of auto indu-
stry in recent years, as well as the general improvement in people's living standard, more strict
demands are put forward on the design of automotive brake. Not only to be able to meet the
basic performance of brake, the design should also satisfy the strict demands on environmental
protection. As a result, improving the brake design is of great realistic significance. This paper
mainly studies the parameteric design of brake design and the secondary development of UG .
First of all, this paper discusses the present situation and development of the research on
CAD technology in domestic and foreign country, meanwhile, reviews the development pro-
cess of the brakes. A feature-based parametric approach is defined to carry out the research and
development on design system of disc brake. Based on defining the principle of discretization,
various structure types of disc brake are disposed of scientific discretization. We plete
sets of brake with typical characteristics and single parts to carry out a three-dimensional
parametric modeling work, and establish a database of parametric model for call.
In the environment of VC + + compiler, using the UG seconda
