【摘要】 本文在详述传统驱动桥设计方法及其特点基础上，详细研究了微型汽车驱动桥智能化设计的实现策略，并构造了基于I-DEAS的微型汽车驱动桥智能化设计软件系统。 全文以软件工程思想为基础，从概要设计、详细设计、几何建模及分析、系统的集成方法四部分阐述了微型汽车驱动桥智能化设计系统的设计思路，最后给出了完整的运行实例。文中对设计参数的层次化定义、约束的分类及其动态化和智能化处理提出了有效的解决方案，并建立了参数信息数据库、尺寸约束函数库和知识约束库。文中还通过对参数约束数学模型的分析并结合驱动桥工程化设计过程，设计出搜索算法和参数更新算法。算法通过调用数据库、函数库和知识库，构成了微型汽车驱动桥智能化设计系统的核心。所形成的软件系统达到了原设计指标要求，并已经过实例测试。更多还原

【Abstract】 After specifying the characteristic of the traditional driving axle’s design method, the implementationstrategy of the minitype automobile driving axle is studied by intelligentize method, and a software system for minitype automobile driving axle based on I-DEAS is established in this dissertation.Based on the software engineering idea, the design ideas for this system are expanded in four parts: concept design, detail design, geometrical modeling and analyzing, the system’s integration. Effective approaches are put forward which to define hierarchical levels of design parameters, classify along with dynamic and intelligent solve various engineering design constraints, and parameters information database, dimension constraint functions database and knowledge constraint database are establishes. By analysing the mathematical model and the design process of driving axle, the search algorithm and the parameter update algorithm are given in this dissertation. These algorithms can call the three databases, and this is the kernel of the system.更多还原
