Diagrams and symbols : some references

Communicating effectively about a technological project involves the use of diagrams. They must be as clear as possible to explain the operating principles.

Each technical field (kinematics, thermodynamics, electrical, electronics, piping, building, etc.) has its own conventions. It is not easy to handle, especially since standardization is not always complete or often remains inaccessible. The site of the Belgian Standardization Office can give you access to standards if your establishment has entered into a consultation agreement (this is the case with UMONS).

Here are some links to find the information you are looking for.

Kinematic links and power transmission components: form SCHL (NBN ISO 3952-1, 3952-2, 3952-3)

Piping and Instrumentation Diagram (P&ID): NBN EN ISO 10628-2, Projectmaterials site

Electrical symbols: IEEE 315 standard

Schémas et symboles: quelques références

Communiquer efficacement au sujet d’un projet technologique implique le recours à des schémas aussi clairs que possible explicitant les principes de fonctionnement.

Chaque domaine technique (cinématique, thermodynamique, électrique, électronique, piping, bâtiment, …) dispose de ses propres conventions et usages et il n’est pas simple de s’y retrouver, d’autant plus que la normalisation n’est pas toujours complète ou reste souvent inaccessible. Le site du Bureau de Normalisation belge peut vous donner accès aux normes si votre établissement a conclu un accord de consultation (c’est la cas de l’UMONS).

7 Mons’quetaires, winners of the Eurobot 2018 competition

Congratulations to the students of Polytech Mons, winners of the Eurobot 2018 contest. This international competition brings together the best 35 national teams selected during national contests: Algeria, Belgium, Canada, France, Germany, Greece, Italy, Morocco, Romania, Russia, Serbia, Spain, Switzerland,Taiwan, Tunisia, United Kingdom

Their engineering background, innovative skills and stong commitment led them to the top of the podium, and into the hearts of their many fans.

Anyone will be happy to watch over and over again the tremendous matches during the competition available from YouTube

Eight final (1:00:00), TURAG (Germany, TU Dresden) video   (188-111)

Quarter-final (1:39:00), CVRA (Switzerland, Ecole Polytechnique Fédérale de Lausanne, Renens) (264-102)

Semi-final (2:15:00), Robotic Legends (France, Polytech Montpellier) (299-280)

Final (3:09:45 and 3:21:20), Polybot (Algeria, Ecole Polytechnique d’Alger) (274-107 and 162-115)

7 Mons’quetaires were unbeaten during the national and international series. This is the first time in twenty years that a Belgian teams win the Eurobot. Just keep in mind that more than 200 international teams are in competition !

Some guidelines for your report

Here are some requirements for any written report.

  • A title must be provided with the following information: subject title, your name (with co-authors, if any), current date, Lab for Machine Design and Production Engineering, Faculty of Engineering, University of Mons.
  • All pages must be numbered (except the title page).
  • Figures and tables should appear with a reference number and a caption. They must be referred to from the text. If your figure or table is based on another author’s, include the appropriate citation at the end of the caption.
  • Bibliographical references should be provided according to a common standard. Have a look to any published book or paper to get a consistent style for your bibliography.


An Ideal Library for Machine Design Projects

Besides the lecture notes of the courses available from the Moodle platform, the students in mechanical engineering could be interested to know which books would be valuable for their personal bookshelf, especially in the perspective of the mechanical design project. It is possible to find valuable information on the Internet, but nothing replaces a printed document to get a complete overview on different technological options or high quality figures.

This is a first selection that will be completed over time. Do not hesitate to recommend your own proposals.

#1. A technological engineering handbook. Mémotech “Conception et dessin”  (Claude Barlier , René Bourgeois, Mémotech, Casteilla, 2011)  is a must-have with more than 650 pages of technical data and accurate design rules.

#2. A bearing catalogue (write to a distributor to get a paper copy)

#3. The Design of Rolling Bearing Mountings by Schlaeffer. (Print and bind it!)

#4. A coursebook on machine design written in English. (Fundamentals of Machine Elements by Bernard Hamrock et al., Machine Design – An Integrated Approach by Robert L. Norton, Mechanical Design Engineering Handbook by Peter R.N. Childs, …)

#5. A collection of printed catalogues for belts, chains, electrical motors, sealings, … (write to distributors)

#6. A general engineering handbook (Dubbel Taschenbuch für den Maschinenbau, available in English; Mechanical Design Handbook by Harold A. Rothbart)

#7. A coursebook on machine design written in German

References #1, #2 and #3 are essential.
