Examensarbetet gick ut på att stötprova ett system för upphängning av kablar och rör i fartyg. Vid stötprovningen monterades upphängningssystemet i en fixtur. Gruppen fick fria händer att utforma fixturen. Med hjälp av Fredy Olssons teorier om produktframtagning utvecklades en fixtur bestående av fyrkantrör. Genom att värdera och selektera bland de lösningar som presenterades i examensarbetet ?Upphängningssystem? BTH-IMA-EX?2000/C-02-SE och andra nytillkomna likvärdiga lösningar, har gruppen kommit fram till och stötprovat ett system, bestående av aluminiumprofiler och vinklar från Bosch Rexroth.

The project has followed a systematic product development process resulting in optimized results for material selection and engineering solutions.

Ett effektivt användande av ett informationssystem förbättrar informationshanteringen inom en verksamhet. För att ett informationssystem ska kunna fungera effektivt krävs att det motsvarar de krav som ställts på informationssystemet av olika intressenter.Requirements Engineering (RE) är en viktig del av systemutvecklingsprocessen för att kunna säkerställa en väl fungerande kravhantering. Use case är en teknik som kan användas som hjälpmedel i RE-processen för att identifiera och dokumentera krav.Syftet med detta examensarbete är att undersöka om use case är tillräcklig som enda teknik för att identifiera och dokumentera krav samt vilka eventuella kompletterande tekniker som används bland systemutvecklare. Resultatet av undersökningen visar att use case-tekniken inte är tillräcklig utan måste kompletteras med andra tekniker för att möjliggöra att samtliga krav kan identifieras och dokumenteras..

Det finns flera olika sätt att konkurrera med en balpress på marknaden. Ett av dessa är att minska cykeltiden för en komplett pressoperation. Härav formulerades en problemställning som lade grunden för examensarbetet. Problemställningen löd ?Metod och anordning för åstadkommande av stegrande presskraft i balpress, Nättraby Verktyg AB.? Sambandet mellan minskad cykeltid och stegrande presskraft gav lösningen med varierande hastighet på pressplattan. För att lösa problemet valdes en frekvensomriktare som omriktar matningsfrekvensen till elmotorn.

The content of the following report is the summarized result of three students thesis at Blekinge Institute of Technology in co-operation with Water Jet Sweden AB. This report will give the reader a description of principles how to measure the abrasive mass flow in a waterjet cutting system. The work began with a visit to Water Jet Sweden AB to get a closer look at the problem. When the analysis of the problem was done the criteria were defined in the form of demands and desires. The main task of the criteria was to guide the search for the solution. The work proceeded with an extensive search for abrasive flow meters along with obtaining information about flow measurement in general. When the search for abrasive flow meters resulted in nothing all the efforts were concentrated on finding a principle of measurement that could cope with the criteria.

The shooting sport is one of the most widespread sports in the world and it isbeing practice in most countries. Based on their own experiences, in competition -and hobby shooting, the client M4Solutions found a demand and need for ashooting target that is manufactured in Sweden.The purpose of the project has been to develop, with the help of Marcus Walldén,two shooting targets from idea to finished product. These two shooting targets,Plate Rack Target and Dueling Tree, would each be equipped with a mechanicalresetting system but will in the future have the ability to be provided with anelectronic resetting system.The project from the client was divided into two theses. One of these two, writtenby Marcus Walldén, focused on the tripod parts and the overall design work forboth Plate Rack Target and Dueling Tree. The thesis that is presented in thisreport have focused on resetting systems, the design of protective plates and otherperipherals for both shooting targets.This work has primarily been in CAD environment where design, constructionand development has been given free rein.

The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.

Information about the risks involved shall be distributed to the people living in the area nearby to potentially dangerous installation. Swedish law stipulates strict requirements on what information should be supplied, but the law itself does not give any guidance on presentation. The main purpose of the study is to give recommendations on how to improve the information brochures. Within the study, eight people working with risk information have been interviewed and seven different risk information brochures have been studied. Also, a theoretical analysis and a practical experiment were performed using brochures from two municipalities.

This thesis of 15 hp has been implemented at Halmstad University, incollaboration with Saab Dynamics in Linköping. Saab Dynamics is a companyoperating in the defence industry where competition is tough. This necessitatesnew ways to increase efficiency in the company, which is the basis for this thesis.Saab Dynamics wants to introduce simulation driven design. Since SaabDynamics engineers have little experience of simulation, required a usermethodology with clear guidelines. Due to lack of time, they chose to assign thetask to students, which resulted in this thesis.The aim of the thesis is to develop a methodology in mechanical design, wherethe designer uses the FE analysis early in the design process to develop thestructures' mechanical properties.

This study is intended to give an impartial view of a young and complex program in Sweden titled Product Innovation Engineering program. The purpose of this program is to increase innovation capability in Sweden that will result in new companies, patents and economic growth. The results from this study might give some direction to future innovation initiatives, but should primarily serve as a tool for the PIEp participants. The study will focus on investigating the creation of the program as well as the development of its strategy. From weaknesses and strengths within the strategy of the program the study should also attempt to show its future potential.

This master thesis presents a Model for Evaluating and Managing Interruption Risks in connection with Business Continuity Planning (BCP), developed for Swedwood International. The model consists of a template with instructions. The model should be easily understood and useful for establishing a plan for BCP. This is achieved by including the contents and procedure of BCP and the main supplychain risks in the model. The purpose of a BCP plan is to describe how an enterprise will return to business as usual after an interruption, e.g.

The thesis was performed at Forsmarks Kraftgrupp AB in the department ofMechanical engineering, FTCM. Forsmark nuclear power plant has had problems with cracks in some of the controlrods which are placed in the reactor at Forsmark 3. To investigate the cause of this,material samples were taken from five of the damaged control rods. This sampling ofthe rods resulted too short rods to be transported in the shipping container to theinterim storage facility for used nuclear fuel in Oskarshamn. Control rods are crucial components in a nuclear reactor, regulating the reactoreffect by blocking or unblocking fuel rods. Control rods which have been in thereactor are always handled under water in order to protect against the radiation theyemit. The task was to design a control rod adapter that extends the control rod sotransport can be performed from Forsmark. The goal of the work was a complete setof blueprints so the control rod adapter can be manufactured and mounted on theshort control rods and then be transported to the interim storage facility. The work began with mapping of how control rods normally being handled from thereactor to the interim storage facility.
