GMCADS语言的研究

The Development of GMCADS Language

GMCADS系统是参考美国目前十分流行的多刚体系统分析软件而研制的一个面向问题的、交互式的通用机械计算机辅助设计系统。为实现GMCADS系统的面向问题和通用性,以及用户使用的方便性,研制了GMCADS语言。GMCADS语言由工程师孰悉的词汇组成,用户应用该语言描述机构模型、提供数据、请求系统分析,从而实现机构的分析与设计。本文介绍了GMCADS语言的产生,讨论了GMCADS语言的特点和语法规则,最后给出了应用实例。

GMCADS, a communication CAD system as well as a directive one to the prombels to be solved, was developed based on referring the softwares for multi-rigid-body system currently applicated in USA. GMCADS language, consisting of words which are familiar to engineers and being programmed with the language, serves users for discribing the mechanism models, praparing data and requiring system analysis so as to perform the analysis and design of the mechanism. The development of the Language, its characteristics andgrammatical rules are dealt with in this paper, with some applied examples recommanded.
