摘　　要：依据信息加工观,研究了机构设计过程的基本思想、方法与技术。通过分析机构设计过程在人脑与计算机中的表征形式、演变过程与相应的信息处理方法,提出信息加工观下的机构设计原理及其CAD技术框架,并就参数化技术下的机构行为分析、基于实例与仿真的性能分析CAD方法进行了探讨。给出了基于语言文字的抽象概念信息处理方法、基于属性特征匹配的抽象与形象表征形式转换方法、基于辅助基准装配的机构方案与性能设计方法。以连杆机构方案创新设计为例,实现了人机交互环境下的智能化、自动化设计过程。Based on view of information processing,the basic ideas,methods and techniques of mechanism design process were researched.Through the analysis of representational forms,evolution and methods of information processing on mechanism design process in the brain and on the computer,the design principle and CAD technology framework of mechanism design on view of information processing were put forward.The mechanism behavior analysis by parametric technology,and CAD methods about performance analysis based on sample and simulation were discussed.Meanwhile,the processing methods of abstract concept based on linguistic reasoning,the methods of transforming abstract expression to be visualized based on attributes matching,the agency programs and performance design methods based on auxiliary reference assembly were given.At last,an example of innovative design on link mechanism was given,which achieved the intelligent and automatic design process under human-computer interaction environment.
