Energy Losses Due to Friction in Gears

Palaghian, L.; Bucsa, M.; Barsan, I. // 2002
This paper presents some theoretical and experimental results regarding the influence of the friction coefficient upon the energy losses in spur gears and worm gears. Tests have been made on medium ...

From Function to Form Using Physical Reasoning

Žavbi, R.; Hansen, C. T. // 2002
The goal of engineering design is to design a product, which fulfils a required function. The Domain theory and chaining of physical laws (way to synthesise solutions) offer a possibility to propose ...

On Knowledge Level Theories and the Knowledge Management of Designing

Smithers, T. // 2002
The design and engineering of new products faces new and difficult challenges due to the globalisation of markets and the rapid development of new technologies. To be competitive, companies must ...

Operating Bolt Load Calculation in Joints of Complex Elastic Structures

Zupan, S.; Prebil, I. // 2002
An improved method for the calculation of actual operating force on every bolt in the bolted joint has been developed. It is founded on the usage of so called “elasticity” and “stiffness” matrices of ...

Prediction of 3-D Crack Growth in Thin Rim-Gears

Kramberger, J.; Potrc, I.; Flašker, J. // 2002
Thin-rim gears with an initial crack in the tooth root, caused by various reasons, are dealt with in this paper. By standard procedures, it is impossible to gain a very good insight into the ...

Product Development Processes Ontology

Mabogunje, A.; Hansen, P. K.; Eris, Ö.; Leifer, L. // 2002
Numerous empirical studies of various product development processes are initiated each year. Most of these rely on vocabularies that have merged partly within their local research community. Though ...

Product Modelling in Early Phases of the Design Process

Korpela, T. // 2002
Product modelling help the designer to communicate about the design problem with his/her colleagues. Models help also the designer to understand entirely the problem to be solved. Aims of the ...

Research on Dynamic Systems – Some Considerations

Björk, E.; Ottosen, S. // 2002
It is a well known fact that interaction and commitment from a range of professions is needed to achieve competitive results in product development projects. Especially when innovative development is ...

Specialized Design Sciences - Questions for the Future

Hubka, V. // 2002
The scope and organization of knowledge about design engineering and the technical systems being designed is presented in Design Science in a general form. The goal of designing is and should be to ...

Task Design and Task Analysis for Empirical Studies into Design Activity

Bender, B.; Kammerer, U.; Pietzcker, F.; Blessing, L. T. M.; Hacker, W. // 2002
In many laboratory studies, design activity has been investigated by observing individual designers or design teams dealing with standardised design tasks. The results are valuable for a better ...

The Application of Design Management Theory to a Real Design Projects

Hollins, B. // 2002
It is proposed that the theoretical models of design management have now moved from being too shallow to being too complex. As a result, they are not being used. Furthermore, they do not include an ...

The Influences of Organisation on Leadership in the Design Process: Results of an Investigation in Five Industrial Companies

Lüdcke, R.; Birkhofer, H. // 2002
The concept of leadership is closely bonded with the concept of organization: one defines and influences the other. The consequences and situations in which these problems arise are shown in this ...

Theoretical Improvement of the Planetary Gear Dynamic Model

Geramitcioski, T.; Trajcevski, Lj. // 2002
The major goal in this work is to improve the planetary gear dynamic model presented in the diseration by Jian Lin presented in the Ohio State University in 2000 . A lumped-parameter model is built ...

Towards a Flexible and Adequate Use of Methods in Product Development

Pulm, U.; Lindemann, U. // 2002
Design methodology has become a major part of research in the field of engineering and offers a large variety of methods in order to establish effective and efficient product development processes. A ...

Contribution to a Theory of Detailed Design

Mortensen, Niels Henrik; Andreasen, Mogens Myrup // 1999


Liedholm, Ulf // 1998
The early phases during design are probably the most important ones. Concept development consists of at least three activities: the establishment of a design specification, functional decomposition ...


Nilsson, Per; Erixon, Gwmar // 1998
The deployment and use of a design method is dependent on the availability of the method. Easy available tools, largely increases its usefulness. Simplicity and clearness together with an easy ...


Erixon, Gunnar // 1997
Modular Function deployment (MFD) is a method for the creation of modular product design, using the concept of "module drivers" [1]. It has been applied in a number of modularisation ...

Boolean Searches

The following examples demonstrate some search strings that use boolean operators:

  • design community
    Find rows that contain at least one of the two words.
  • +design +community
    Find rows that contain both words.
  • +design community
    Find rows that contain the word “design”, but rank rows higher if they also contain “community”.
  • +design -community
    Find rows that contain the word “design” but not “community”.
  • +design ~community
    Find rows that contain the word “design”, but if the row also contains the word “community”, rate it lower than if row does not.
  • +design +(>community <decisions)
    Find rows that contain the words “design” and “community”, or “design” and “decisions” (in any order), but rank “design community” higher than “design decisions”
  • design*
    Find rows that contain words such as “design”, “designs”, “designing”, or “designer”.
  • "some words"
    Find rows that contain the exact phrase “some words” (for example, rows that contain “some words of wisdom” but not “some noise words”). Note that the " characters that enclose the phrase are operator characters that delimit the phrase. They are not the quotation marks that enclose the search string itself.
