Validating a reconfigurable assembly system utilizing virtual commissioning
Published ArticleSouth African manufacturing companies today need to be more sophisticated technologically to compete for global markets. The latest trend in automation and manufacturing emerges in the form of reconfigurable systems. The aim of this paper is to show the development of a reconfigurable assembly system and using virtual commissioning to plan, validate and optimize it. To achieve this "DELMIA" software was used to create a virtual simulation environment to verify an assembly cell from such a system as a case study. Simulations were conducted to verify software functions, device movements and operations, and the control software of the system. As a result, it was found that virtual commissioning is an excellent tool for predicting how the system will function, verifying system code early, and rectifying design flaws. This will enable manufacturing companies to be more competitive, ensure increased productivity, save time and ensure them an advantage over their competition
Windlastnormen nach 1992 Vortragsband
Mit dem Schwerpunktthema wurde die einheitliche technische Normung in der Europaeischen Union angesprochen. Hier steht einerseits die Europaeische Vornorm 'Windeinwirkungen' im Blickfeld, die einen Teil des Eurocodes 1 'Entwurfsgrundlagen und Einwirkungen auf Tragwerke' bildet. Ihre Stellung als technische Regel im europaeischen Recht ist von zentraler Bedeutung fuer die zukuenftige Arbeit des Tragwerksplaners. Andererseits ist der Abgleich mit den nationalen Normen eine wichtige Aufgabe in der Erprobungsphase. Deshalb wurde auch ueber neue nationale Entwicklungen, z.B. in den Niederlanden und der Schweiz, berichtet. Der Berichtsband der Tagung mit dem Eurocode wurde erst herausgebracht, als eine verabschiedete Fassung vorlag. Die Verabschiedung der Windlastnorm durch das Europaeische Komitee fuer Normung CEN, TC250/SC1 hat laenger gebraucht, als 1991 abzusehen war. Sie erfolgte erst im Dezember 1993, nachdem - nicht so sehr im technischen Inhalt aber doch in der Anwendung der Regeln - noch wesentliche Vereinfachungen eingebracht worden waren. (orig./HP)The D-A-CH '91 conference discussed the problem of standardisation in the European Union in the field of wind loads. On the one hand, there is the draft European standard 'Wind Effects', which is part of Eurocode 1, 'Design Fundamentals and Effects on Supporting Structures'. As a technical rule under European law, it is of central importance for the future work of planners of supporting structures. On the other hand, matching with national standards will be an important task in the trial phase. This is why also new national developments, e.g. in Switzerland or the Netherlands, were reported at the conference. This conference volume containing the Eurocode was not published until an official version of the Eurocode was available. This took longer than expected, due to the fact that simplifications had to be made not in the technical details but in the application of the regulations.
