Konstruktion Signalgenerator

SAAB Aerotech division FGR in Arboga builds and develops equipment and components used in both military and civilian applications. To build a test system for a specific project that SAAB is responsible for requires a simple signal generator that can provide a pulse modulated signal. The need to buy a new advanced signal generator for example from Agilent is not as profitable as the instrument is expensive and contains features that SAAB does not require in their applications and test systems. That was the reason why SAAB offers two students a thesis where the goal is to construct a signal generator in accordance with what SAAB requests.This thesis contains several different phases. The first step was a meeting with our supervisor Mats Bergman and by reading the data sheets for components to be used in the project, with these information and specifications that we have received from SAAB we started to construct the signal generator.What we did during the construction work was to simulate and draw a schematic to be able to design the circuit board.

Mätdatainsamling

Rapid Granulator is one of the world's largest producers of granulators, which is a kind of grinderwho grinds discarded plastics to granules which later can be reused when pressure molding plastics.The company wanted help in developing a new, or alternatively extending their previous,measurement equipment. The old equipment was hard to use, required changes in the code fordifferent measurement scenarios and had a limited array of measuring quantities. Rapid had an ideaof a similar concept only with a greater number of input ports, better range of applicable sensors andan advanced yet easy to use interface. The system is supposed to be placed at Rapid's test departmentwhere it will be used as a tool for finding faults and provide data which can be used for furtherdevelopment of the granulators.The project's members accepted the task and immediately began searching for suitable componentsfor the system. After the search was completed a list of costs, limitations, sensors, I/O's anddevelopment environment was presented to Rapid's staff.

Kvalitetsförbättringar och Emballageinstruktioner

This report is the result of a thesis carried out at the Department of Innovation, Design and Technology (IDT), at Mälardalen University on behalf of ABB AB Machines.The year was 1988 when ASEA and Brown Boveri formed a joint venture under the name ABB (Asea Brown Boveri).We perform our thesis at the division Discrete Automation and Motion where they primarily develops, manufactures and sells synchronous and asynchronous AC motors and generators.The main purpose of this thesis was initially to write a general packaging instruction, but the priority changed to develop more specific packaging instructions for Rotors, Stator gables, Bearing support and Outer Cover (plates) instead.The work started off to deal with a problem about that the staff had to start its work to grind away rust on the stator gables due to those stored outdoors. The result was mainly an investment in a new gable Rack so that the material can be stored inside, as well as a packing instruction as it was originally intended.The problem on the bearing supports were that the staff thought it was demanding and difficult to clean them from the rustproofing they were greased in. If it is not possible to remove all rust protection it can cause the paint to not attach properly. After having compared with similar articles a test were done to order a pair of bearing supports without corrosion inhibitor, which gave good results. This initiative also set in motion a process to do the same for more different items.For special pallet, a survey were made of the process with two different VSM and a calculation of how much ABB would earn at ordering more special pallets than getting the material delivered on the A-pallets.

Kvarteret Veiberg : från sluten innergård till öppen mötesplats

The object of the thesis is to propose a new design for the neighbourhood of Veiberg that is situated in the small Norwegian town Jessheim. My approach was to first make an analysis of the whole community and the structure of the town, and then gradually focus on the actual neighbourhood to continue the research there. On the basis of my research the block will be redesigned. The research will lead to a well-planned design of the neighbourhood, which will adapt it to its surroundings in a sustainable and constructive way. The project will lead you through the history of the town and the intentions and aims of the municipality. The project also examines the structure of the town and the function of the neighbourhood in the town today as well as investigation of the history, the structure and the qualities in the area.

Brandvägg: design av front till chassi

När man kopplar en dator eller ett lokalt nätverk av datorer till ett annat nätverk, t.ex. Internet, måste man vidta vissa åtgärder för att förhindra att inkräktare får tillgång till resurser eller material som kan anses hemligt eller känsligt. För att uppnå detta måste en s.k. brandvägg installeras. Dess uppgift är att se till att bara godkänd trafik tillåts passera mellan nätverken och att otillåten trafik blockeras och loggas.

Utveckling av fångapparat till kuggstångshiss

Alimak Hek tillverkar och säljer bl a kuggstångshissar. Kuggstångshissar skiljer sig från konventionella linhissar genom att de inte lyfts av vajrar, utan vandrar längs en kuggstång. Detta innebär att hissarna kan bära drivningen i direkt sammanknytning till hisskorgen, vilket i sin tur medför att de snabbt kan resas och användas även i svåra miljöer. Eftersom de inte behöver lyftas av en vajer är de kapabla att lyfta högt och tungt.Men likt andra typer av hissar är kravet på säkerhet högt, bl a måste hissarna utrustas med en nödbroms, kapabel att bromsa hissen om nöden kräver. Alimak Hek använder idag nödbromsar som bygger på en konstruktion som ursprungligen utvecklades på 70-talet, men genom årens lopp har tillägg gjorts för att klara nya krav.

Industrialisering av konsumentprodukt : Från inkommande material till färdigvarulager

This report examines the industrialization of a newly developed household machine on behalf of Technogarden Engineering Resources in Karlstad, Sweden. The report is a part of the final course in the Bachelor Program in Mechanical Engineering at Karlstad University and takes place in spring 2014.An innovator, an investor and a engineering consultant firm have through collaboration developed a new type of gruel machine. The product is in its final stage of construction and is planned to be manufactured in a production located in Sweden, autumn of 2014.To compete against today?s trend in outsourcing manufacturing to low cost countries for better profitability, the industrialization of the gruel machine must be done with a minimum amount of resources in order to become successful, which also describes the problem of this study. Using pre-study material in form of Lean production literature, visiting a successful production site and gathering data from involved engineers a specification was developed which describes what this industrialization must achieve and which requests can be accomplished.
