    Verification that the various parts of an assembly fit together correctly is an important use of CAD systems. This can also extend to mechanism simulation. It can, however, be time-consuming if the CAD system is not sufficiently sophisticated. An alternative is to perform the assembly using separate software based on simpler models of the individual parts. The assembled version can then be transfe... View full abstract»

    Describes a CAE package, supplemented by a powerful database handler for storing geotechnical data of any given geo-map for the design, analysis and management both rigid and flexible pavements. Pavement design and analysis are based on the American Association of State Highway and Transportation Officials (AASHTO) guide. The cost and performance of different maintenance strategies on flexible pav... View full abstract»

  • Simple turned part design and manufacture with parametric CAD/CAM techniques

    Publication Year: 1991, Page(s):147 - 152

    Reports mainly on work carried out at Heriot-Watt University concerning the 'integration' of proprietary CAD/CAM software in order to produce turned parts from initial design data with minimal operator input. Libraries of standard parts are often responsible for the usage of a large amount of processor memory. One solution to this problem is to regenerate the graphics of each part using a parametr...

  • Communicating design representations: the role of interpretation

    Publication Year: 1991, Page(s):153 - 159

    The development of integrated computer systems in the fields of architecture, engineering and construction (AEC) requires a viable scheme for data exchange between professional groups. Data exchange capability has two essential components: representation standards and feature extraction. A representation standard is an agreement among AEC professions about a common problem description language. Fe... View full abstract»

  • Report on existing CAD support for programmable devices

    Publication Year: 1991, Page(s):160 - 166
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (531 KB)

    Computer-aided design (CAD) software for programmable logic devices (PLDs) provides the link between design for programmable logic and the fuse patterns required to program the devices. This article reports an investigation into the current state of CAD support for PLDs. The study was necessary background to defining the requirements of a logic synthesis system for PLDs. Aspects of PLD CAD systems... View full abstract»

  • Computer-integrated manufacturing information system for VCR testing

    Publication Year: 1991, Page(s):173 - 179
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (406 KB)

    An information system in the form of a local area network (LAN) was designed for a video cassette recorder (VCR) manufacturing environment. This system uses the Ethernet approach with hardware components satisfying IEEE Standard 802.3. The database component can produce reports, graphs and statistical quality control charts. The network communications component allows message sending screen captur... View full abstract»

  • An expert system for the preliminary design of offshore topside superstructures

    Publication Year: 1991, Page(s):167 - 172
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (752 KB)

    Discusses a knowledge-based expert system IPDOTS implemented for the preliminary design of offshore topside superstructures. This study is an extension of the study, described in an earlier article into using an expert system for the preliminary design of offshore jacket structures see ibid., vol.7, no.1, p.7-11 (1991). This article concentrates on the architecture of IPDOTS and how it can assist ... View full abstract»
