An unfortunate aspect of engineering education in general, and turbomachinery education in specific, has been the difficulty of incorporating the design aspect of instruction with the time-consuming components that make up theoretical instruction. The primary reason for this difficulty is the extremely limited time (typically three months) allocated to teach turbomachinery as a senior-level quarter or semester technical elective. It is desirable to develop an educational design tool that can be simultaneously exercised by a student to perform various design tasks and function as a means of theoretical instruction. Such a tool can permit the students both greater depth and breadth of exposure and may be subsequently used by the students in their future capacity as professional engineers. In this paper, this tool is illustrated by several applications of a commercial “graphical spreadsheet” software package (MathCAD, though others such as Mathmatica and Macsyma are appropriate as well). Some graphical spreadsheet design tools are presented, and these tools are applied to the analysis and design of a radial pump, centrifugal compressor, and radial-inflow turbine.

This paper reports on a knowledge rich design repository system. Current design tools and methodologies are reviewed and used to identify necessary design knowledge to populate a design repository. Building on previous research, an operational design repository is reviewed. The design repository system demonstrated includes a single point of entry application for product information, a relational database for archiving design knowledge and web-based tools. Web services are used to support design knowledge retrieval through search, browse and real-time design tool generation. From the repository interface, design tools such as bills of materials and design structure and function component matrices are generated. The output design tools are tested in real world design applications and validated. The result is a useful tool — applicable to several phases of product design.

This paper builds on previous concept generation techniques explored at the University of Missouri - Rolla and presents an interactive concept generation tool aimed specifically at the early concept generation phase of the design process. Research into automated concept generation design theories led to the creation of two distinct design tools: an automated morphological search that presents a designer with a static matrix of solutions that solve the desired input functionality and a computational concept generation algorithm that presents a designer with a static list of compatible component chains that solve the desired input functionality. The merger of both the automated morphological matrix and concept generation algorithm yields an interactive concept generator that allows the user to select specific solution components while receiving instantaneous feedback on component compatibility. The research presented evaluates the conceptual results from the hybrid morphological matrix approach and compares interactively constructed solutions to those returned by the non-interactive automated morphological matrix generator using a dog food sample packet counter as a case study.

Object Oriented Languages

Abstract The need for superior design tools has lead to the development of better and more complex computer aided design programs. Two of the more important new developments in application tools being investigation are Object Oriented Languages, and HyperMedia. Object Oriented Languages allow the development of CAD tools where the parts being designed and the design procedures specified are conceptualized as objects. This allows for the development of design aids that are non-procedural and more readily manipulated by the user trying to accomplish a design task. HyperMedia allows for the easy inclusion of many different types of data, such as design charts and graphs, into the tool that are normally difficult to include in design tools programmed with more conventional programming languages. This paper explores the development of a computer aided design tool for the design of a single stage gear box using the development HyperCard® environment and the HyperTalk® programming language. The resulting program provides a user friendly interface, the ability to handle several kinds of design information including graphic and textual, and a non-procedural design tool to help the user design simple, one stage gear boxes. Help facilities in the program make it suitable for undergraduate instruction in a machine elements design course.

Energy Strategies

Getting wood for cooking, heating, processing into charcoal and/or selling is a fundamental part of most household survival strategies in Developing Countries. Entangling in complex and dynamic ways local and global ecosystems, poverty, technology and business Wood Fuel Energy Systems (WES) are fundamental and require simple to use design tools to support the strategic and optimised used of available socio-ecological resources/assets. However, there are very few tools able to support relevant actors (e.g. charcoal makers, experts, policy makers) in that task. To bridge that gap the 2MBio, a participatory conceptual design tool to support the strategic design of WES, is introduced and its practical results in Mozambique presented. The 2MBio explicit in a simple and intuitive layout the set of necessary and sufficient resources/assets required to produce comprehensive and meaningful WES designs/strategies, which represent in themselves a strategic asset, while further stimulates knowledge and creativity as a tacit asset.

Abstract The Guelph design tool for vegetative filter strips, GDVFS, is a toolkit for the analysis and design of vegetative filter strips (VFSs). The upland hydrology model UH and the vegetative filter strip model VFSMOD (the two main components of GDVFS) were adopted from an existing interface (VFSMOD-W), and new nutrient and bacteria transport add-ons for UH and VFSMOD were incorporated into GDVFS. Other utilities and tools were also included in GDVFS to provide a capable toolkit for the analysis and design of VFSs. The published evaluation of computational procedures used in GDVFS indicates that these procedures perform very well in the estimation of VFS sediment and phosphorus removal efficiencies. According to these results, comparison of the predicted and observed values for sediment and phosphorus removal efficiencies indicates 10 and 20% error, respectively. This paper provides descriptions on the capabilities and methodology followed in the GDVFS toolkit.

Experimental and computational modal analysis has been completed as part of a larger project with the ultimate goal of understanding MRI vibration and implementing passive vibration isolation in the MRI machine support structure. The specific purpose of the modal analysis is to extract natural frequencies (eigenvalues) and mode shapes (eigenvectors) of the MRI support structure in order to validate the computational model of the base against the experimental results so that the former may be used as an analysis and design tool. From the model, the resonance points of the MRI support structure are determined within the expected frequency ranges of excitation.
