Professional Characteristic

Close framework structure becomes recently a competitive solution for taxiway bridges. Due to no pile foundation construction, it has short duration and significant economic benefits. The development of close framework CAD system adopts Visual Basic and bases on secondary development interface in AutoCAD VBA to draw construction plans, such as structure diagram, bridge layout, prestressed tendons and ordinary reinforced chart. Another feature is the automatic generation of materials amount Excel tables and model for finite element analysis. The main program code of graphic object realization and deign parameters import are described. For the unique professional characteristic in airport project, the software system has a considerable engineering prospect.

Cad Cam

The precision cam divider is mainly used for intermittent indexing step motion between two vertical staggered shafts and extensively applied in machinery of textile, package, tobacco, food, pharmacy and machining center, etc. [ [. With progress of modern science and technology, higher speed, efficiency, life and quality are required for mechanical transmission mechanisms on automats and automatic lines, as a result, higher requirements are raised for properties of the precision cam divider. In spite of advantages of high transmission speed, high locating precision, high indexing precision, good reliability, good dynamics performance, simple structure and long lifetime, etc. of the precision cam divider, artificial design is very cumbersome, in which design and machining of globoidal indexing cam are more complicated [ [. This paper develops CAD/CAM system for globoidal indexing cam by means of Pro/E system development platform and parameterizes design of globoidal indexing cam and transposition disc so as to simplify design interface and shorten design cycle of product, and mean while performs dynamic assembly, simulation and test of product performance to improve product quality and operating efficiency.

Cad Modelling

Abstract CAD modelling can be referred to as the process of generating an integrated multiple view model as a representation of multiple views of engineering design. In many situations, a change in the model of one view may conflict with the models of other views. In such situations, the model of some views needs to be adapted in order to make all models consistent. Thus, CAD models should be capable of adapting themselves to new situations. Recently, agent based technologies have been considered in order to increase both knowledge level and intelligence of real and virtual objects. The contribution of this paper consists in introducing the intelligent agents in intelligent CAD modelling. The proposed agents are elementary geometrical and topological objects. They incorporate the functions of observation, decision and action, and possess their own knowledge. Agents have the capacity of communication and inference based on the feature grammars. They are modelled as bio-dynamic objects that enjoy the properties of fusion, division and multiplication. Being aware of the context, the proposed agents interact to form potential regional transitory communities, called regions. Being aware of their belonging in a region, agents interact by generating virtual links (virtual extensions). These virtual links produce: (a) fusion of agents, (b) division of agents and c) multiplication of agents. The emerged agents interact with the other agents in a region to recognize each other and to form specific sub-communities, called intelligent features. From a CAD software development point of view, this paper advocates the idea of a new phase of CAD system development based on the agent-oriented programming (AOP) paradigm. Highlights This paper proposes the agent paradigm for intelligent CAD modelling. Second section presents the state of art. In the third section, using the linguistic hypothesis of product design, a feature modelling formalism is presented. Fourth section presents a formal model for agent modelling. In the fifth section, agents for feature generation and modelling are formalised and modelled. The sixth section presents the application of the method. Finally, in the last section, the conclusion and future developments are proposed.
