Input data management is a time-consuming and costly for Discrete Event Simulation (DES) projects. According to research studies, the input data phase constitutes, on the average, can account for over a third of the time of an entire simulation project. This paper presents a newly developed Open Source (OS) tool, called the Knowledge Extraction (KE) tool that automates the input data management in...
Considering the weaknesses in the current higher vocational school (HVS) electrical engineering experiment course, we put forward a scheme for building the Web-based virtual experiment system. In this paper, we illustrate the design plan and structure of the electrical engineering virtual experiment system, as well as expose the key technology, where both 3DsMax and Virtools are employed to build...
To improve the speed and accuracy of case retrieval of spade punch planter for digital design, this paper analyzed the design process of spade punch planter, proposed a method to design knowledge representation based on object oriented theory, and elaborated the construction methods of knowledge and resource database which include multi-level case database, knowledge rules database based on association...
The relief models made by the common modeling software are difficult to be consistent with the digital terrain model (DTM) and cannot fully express their morphological characteristics (such as the form, the structure, the spatial distributions and so on). In view of the above question, this paper advances an automatic modeling method of 3D relief symbols with building-up style. A component library...
Based on Pro/E's designing concept of parameterization and character, regards Visual C++ 6.0 as developing environment, the paper developed a parametric system combining with the character of gear shaft. Using visualization technology, the system can input design parameter in man-machine interactive interface to generate three-dimensional model rapidly. Through this method, we can reduce repeating...
We propose a new system for building a 3D database for human teeth. Real extracted human teeth are scanned using a cone-beam CT scanner to build. The teeth models are segmented from the resulting images by means of level sets. The database includes 3D models of these teeth after minimizing global differences between the models. An affine transformation function is used to model the differences between...
The solution of shipbuilding enterprise ERP problem is proposed under the dimensional visualization environment. In the VB environment, CATIA and Access database is developed for the second time, and Digital Shipyard Resource Optimization module is designed. System arrangement is evaluated; the load on the production line, the buffer capacity and bottleneck are analyzed. System fault and repairing...
The paper presents loop closure methodology to disclose the variation window of fab for a technology to robust design for manufacturability. With automatically screened fab raw data, the clean data is collected for many months allowing good prediction of future results for overall fab capability and also used for monitoring fab performance versus design libraries and technology specs to ensure that...
During the engineering design and teach about engineering drawing, it is often to help our thinking in space by model, when we read or draw engineering design. Special manufacture and easy damage result of high cost of making and remaining. In this paper, a new method is put forward to develop the model library by combining Cult3D and online management, which take use of advantages of network in share...
High voltage switchgear products always produce a great lot of parts models and design information in digital design. And such products have the characteristics of series and complexity. Therefor, this paper takes a certain series of outdoor HV isolating switchgear as an example, and multi-attribute mapping parts library system has been researched and developed based on C/S mode for corporate design...
Mass customization product design in the virtual design system based on B/S mode is studied. The approach is based on prototype product parameterized modeling and VRML language, and is supported by Eletrical Apparatus Product Intelligent Design System (IDS). The IDS processes the customer's requirements of products and produces a design result document including the designed product structure and...
Based on a close research of the interior representation of CAD model in MDT, ObjectARX application program is developed using the development tools of ObjectARX and MDT API offered by Autodesk Inc in MDT environment, according to which the database is expatiated particularly. So that this thesis picks-up the interior topological and geometrical information of model expressed in the boundary representation...
Pro/TOOLKIT and FamilyTable provided by Pro/ENGINEER and Visual C++6.0 are utilized to develop three-dimensional standard part library of riveting joint according to national riveting joint standards. Feature based modeling and FamilyTable are used to construct three-dimensional riveting joint part library. The interface between Pro/ENGINEER and MFC is developed using DLLs to establish a man-machine...
Document management is an important component of product data management. In order to improve the level of document information processing and meet the function requirements of product, such as document query, document browsing, information sharing and version management, etc, based on the study of document management in data management systems, this paper adopts advanced B/S architecture and ASP...
It is a challenging task for the creation of 3D digital content production that often requires some artists and directors to work together, and needs to store and manage many project fodders. In this paper, we design a mechanism that use instant messaging and files management for the 3D digital content production development project, and solve several key technologies in the production development,...
Computer-aided fixture design (CAFD) system is usually developed at a special CAD platform, which limits the data exchange between different CAD systems. How to transform data in modular fixture (MF) elements library of CAFD system from one CAD system to another is focused on in this paper. The tabular layouts of article characteristics (SML)-based method is adopted in the following ways: firstly,...
In this paper, we describe a digital library initiative for non-textual documents. The proposed framework will integrate different types of content-repositories - each one specialized for a specific multimedia domain - into one seamless system and will add features such as automatic annotation, full-text retrieval and recommender services to non-textual documents. Two multimedia domains, 3D graphics...
In this paper we present a new vision-based approach for transmitting virtual models for augmented reality (AR). A two dimensional representation of the virtual models is embedded in a printed image. We apply image-processing techniques to interpret the printed image and extract the virtual models, which are then overlaid back on the printed image. The main advantages of our approach are: (1) the...
