According to the geometricl characteristic of sheet metal , itsfeature has been defined and classified . then the feature - class system and product data model of sheet metal is constructed by means of oriented object modeling technology 针对钣金零件的特点,对钣金件进行了特征分类并采用面向对象的建模技术提出了钣金件的特征类体系和产品特征模型。
In this paper , the modeling technology for 3d geometrical object and the maneuvers of loading scene objects are analyzed and researched , and the view scene system software for automobile driving training simulator is developed 本文对视景系统中的三维几何对象的建模技术和场景的调度机制进行了分析与研究,并且开发了汽车驾驶训练模拟器视景系统软件。
Visual object - oriented modelling technology is used to encapsulate all the five views as a series of uniform object model . thus , through depicting the relationships among views by the association and invocation among objects , the multi - view model integration problem is well solved 采用面向对象的建模技术将各个视图模型共同封装成对象模型,通过对象之间的关联与调用来实现模型视图之间的关联,从而有效解决了多视图模型之间的集成问题。
According to the draft of iec61850 , some technologies such as oom ( object oriented model ) , mms ( manufacturing message specification , iso9506 ) , dde ( dynamic data exchange ) and opc ( ole for process control ) are involved . the thesis has done some experimental work with them 根据iec61850的草案版本内容, iec61850涉及到的主要技术有面向对象的建模技术、制造报文规范( mms ) 、客户端通信接口技术dde以及opc技术等。本文对它们进行了尝试性的开发工作。
After anatomizing the two kind techniques , we choose seven kind patterns to express the five dem - models . in order to realize the erp system , we also utilize the aibas , which is a kind of case ( computer aided software engineering ) technology , the most important is aibas provide us lots of " groupware cell " , which help us to construct the groupware , also the paper introduces aibas software in details too 课题在进行动态企业建模时,还采用了uml这样一种面向对象的建模技术,通过对比分析uml建模机制和dem建模原理后,选择了其中一部份建模表达方式来建立dem建模所需的五类模型。
