The aim of this thesis is to simulate the action of electrodynamic forces on current carrying path and a movable contact of the circuit breaker OEZ Modeion BH 630NE. For the calculation there is used the simulation program Ansys Maxwell. The first part is devoted to theoretical analysis of electromagnetic forces on a conductor in a magnetic field. Further I discuss the constructional design of the circuit breaker itself, especially the current path and the contact mechanism. In the next part there is (with using program Autodesk Inventor) created a simplified 3D model of the current path including an arc chamber. With program Ansys Maxwell then there is performed simulation of the acting of forces in each mode. This is magnetostatic and transient analysis for symmetrical and asymmetrical flow of the fault current. In conclusion the results obtained are evaluated and processed in the tabular way.

Landschaft und Archäologie im virtuellen 3D-Modell Beispiel „Ethno-Nature Park Uch-Enmek“ (Altai, Russland)Schmid, Marcel 11 January 2012 (has links)
Im Rahmen dieser Diplomarbeit entstand in Zusammenarbeit des Instituts für Kartographie der Technischen Universität Dresden und Archäologen der Universität Gent in Belgien ein dreidimensionales Landschaftsmodell einer Teilregion des Naturparks „Uch-Enmek“, gelegen in der Republik Altai. Diese Region beinhaltet die wichtigsten und größten bekannten Begräbnisstätten skythischen Ursprungs, für die es gilt, den Bekanntheitsgrad und das Bewusstsein dieses kulturellen Erbes durch diese Arbeit zu steigern. Im Zuge dessen wurden wichtige Geodaten, unter Berücksichtigung der prägenden Geoelemente einer Landschaft, in einem Geoinformationssystem zusammengetragen, um die Ausgrabungsstätten ergänzt und verfeinert und schließlich zu einem digitalen Landschaftsmodell ausgebaut. Die Wandlung zu einem dreidimensionalen Landschaftsmodell durch Hinzunahme von 3D-Objekten, wie Gebäuden oder Bäume, wurde in einer professionellen 3D-Software durchgeführt. Zur Visualisierung des Endproduktes wurden aus dem resultierenden 3D-Modell statische Bilder und eine Animation erstellt. Zukünftig können die Ergebnisse genutzt werden, um einen Internetauftritt des Naturparks zu ermöglichen. / Within the scope of this diploma thesis, a three-dimensional landscape model of a part of a region located in the nature park „Uch-Enmek“ (situated within the Altai Republic), was generated in cooperation with the Institut for Cartography of Dresden University of Technology and archaeologists of the University of Ghent in Belgium. The area of interest contains the most important and well-known burial mounds, that origin back to Scythian history. Aim of the thesis is to increase the degree of popularity and the awareness for this cultural heritage. In this case, important geodata were collected within a geo-informationsystem, with respect to characteristic geoelements of a landscape. The geodata were replenished and improved around the archaeological excavation and built up to a digital landscape model. The conversion to a three-dimensional landscape model by adding three-dimensional objects, like buildings and trees, was executed with the help of a professional 3D-software. To visualize the final product, static images and an animation were generated as results out of the 3D-model. Prospectively, the achievement can be used to establish an internet presentation of the nature park.

Kvalitetssäkring av objektsbaserade IFC-filer för mängdavtagningar och kostnadskalkyler : En fallstudie av levererade konstruktionsmodeller, vid Tyréns AB Stockholm / Quality assurance of object-based IFC-files for quantity takeoff and cost estimating : A case study of delivered construction models, at Tyréns AB StockholmGustavsson, Sam, Johansson, Filip January 2013 (has links)
Att utföra kostnadskalkyler och mängdavtagningar utifrån objektbaserade 3D-modeller har visat sig vara problematiskt då modellerna inte uppfyller de förväntade kraven på informationsnivå. De bristande modellerna leder till en större osäkerhet då kalkylatorn skall upprätta kostnadskalkyler, vilket utgör bakgrunden till de frågeställningar som rapporten utgörs av. Projektet Biomedicum, som skall bli det toppmoderna laboratoriet åt Karolinska Institutet bedrivs som ett fullskaligt BIM-projekt, där de objektbaserade 3D-modellerna utgör underlaget för bland annat kostnadskalkyler i systemhandlingsskedet. Kalkylatorn i projektet, har uttryckt ett missnöje gällande kvaliteten i modellerna, och menar på att det finns stora brister som leder till att risken för att osäkra kalkyler upprättas ökar. Denna rapport kommer således att se över hur det är möjligt att kvalitetssäkra en objektbaserad 3D-modell i IFC-format i programvaran Solibri Model Checker, utifrån de projektspecifika kraven som råder i projektet. Rapporten utgörs av en fallstudie och en litteraturstudie, och till viss del även av intervjuer. I fallstudien undersöks det om Solibri Model Checker är kapabel till att kontrollera modellerna utifrån de projektspecifika krav som råder i projektet, samt att analysera resultatet av kontrollerna som har utförts. Intervjuerna i sin tur har legat till grund för ett antal problem som har ansetts vara relevanta för rapporten. Problem som kan härledas till juridiska svårigheter, avsaknad av en gemensam branschstandard, meningsskiljaktigheter kring innehållet i en objektbaserad 3D-modell etc. I fallstudien har det visat sig att 3D-modellerna är bristande ur kalkylsynpunkt. Detta leder till svårigheter och osäkerheter då Skanska upprättar kalkylerna. Anledningarna till detta är flera. Det handlar bland annat om att konstruktören använder sig av en modelleringsteknik som inte är anpassad för kalkylering, men även att det inte finns tydliga riktlinjer om vilken information som bör finnas i objekten i systemhandlingsskedet, vilket har framgått under intervjuerna. Det har även framgått under intervjuerna, att ett avgörande problem som kan anknytas till att modellerna är av bristande kvalitet ur kalkylsynpunkt, är på grund av att det inte har ställts krav tillräckligt tidigt i processen. Vad som är viktigt för att få en fungerande process där de objektbaserade 3D-modellerna skall användas för mängdavtagningar och kostnadskalkyler, är att i ett tidigt skede fastslå vilken information som behövs i objekten för att trovärdiga kalkyler skall vara möjliga att upprätta. Vikten av att det finns en tydlig IT-handledning är även stor, då det är handledningen som ligger till underlag om vilken information som skall finnas med i modellerna. / To perform quantity takeoffs and cost estimates based on 3D models is problematic, if the models do not meet the expected demands of information. The weaknesses of the models leads to uncertainty when the calculator will establish cost estimates, which forms the background to the issues that the thesis constitutes. The project Biomedicum is conducted as a full-fledged BIM project, where the object based 3D models are the basis for cost estimates in the system phase. The calculator in the project has expressed dissatisfaction regarding the quality of the models, and believes that there are major flaws that lead to the risk of uncertain calculations increasing. Of this reason, this thesis will analyze the possibilities about ensuring the quality of an object based 3D model in IFC format, by using the software Solibri Model Checker. This thesis consists of a literature review, interviews and a case study. The case study examines whether Solibri Model Checker is capable of checking the models based on the project specific requirements, and to analyze the results of the checks that have carried out in the case study. The interviews have been the basis for the number of problems that have been considered relevant for the thesis. Problems that can be traced to legal difficulties, lack of a common set requirements, disagreements about the content of an object based 3D model etc. The case study has shown that the 3D models are inadequate to perform cost estimates, which leads to difficulties and uncertainties in the calculation process. There are several reasons for this. The designers of the project have used wrong modeling technique for quantity takeoff and cost estimating. But also that there are no clear guidelines as to what information should be included in the items in the document stage system, which has emerged during the interviews. It has also emerged during the interviews that crucial problems that may be linked to the models are of poor quality, because it has not been required early enough in the process. What is important to get a working process in which the object-based 3D models to be used for quantity takeoffs and cost estimates, is that in the early stages determine what information is needed in the objects to credible estimates will be possible to establish. The importance of a clear IT manual is also great, as it is the manual who serves as the basis of the information to be included in the models.
