The report presents a thesis carried out on behalf of the company SAAB Training and Simulation which is situated in Huskvarna. The authors of this report are going to graduate as mechanical engineers focusing on product development and design, and this thesis should reflect the knowledge obtained during the education. The assignment, given from the company was to develop a concept of a stand that will constitute as a part of a mobile system for target practice. The reader get to follow throughout the project and can hopefully learn from the smart solutions and approaches that have arisen during the process.Today SAAB doesn?t have a mobile application in their portfolio that utilizes the benefits of their sensor measuring system, also called the LOMAH-bar.

Gormsson - En symaskin för nybörjare

We are getting smarter. Our knowledge of the world around us is increasing rapidly and our population spend a big portion of their time in school studying it. But art and craft are moving out to give room for more theoretical subjects. Today many of us can not even fix a torn shirt without help. We buy new ones, they are cheap enough.

Framtagning av en remdriven växellåda till en häcksax

The project was performed in collaboration with Husqvarna, one of the world?s leading manufacturer in the market of electric outdoor products. The report is a thesis work of a bachelor mechanical engineer program, in the field product development and design.The project is a study of the development opportunities within drive belt for a gear driven gearbox to one of Husqvarnas petrol powered hedge trimmers. A big part of the project was also to find combinations of materials for all components in the gearbox, to reduce weight and maintain or improve the performance of the system. Belt drive was of interest to investigate as an alternative solution to the current design that can reduce wear on the system at a performance test performed in the company before the product is released to market.

Strängluftning av vallfoder : Inverkan på ensilagets torkningförlopp, spill och smörsyratillväxt

When harvesting ley you hope to get a fast drying and a faster harvest. If there is a system with round bales, you need to have a dry matter close to 45 %. To make this as fast as possible, there is made a machine which pick up the grass with an pick-up. It turn the grass over and put it behind the machine (figure 2 and 4). There are few tests to prove the efficiency of this machine.

Fårens anpassning till värme och kyla

Får finns i stora delar av världen och i helt olika miljöer. För att klara av att leva väl under så vitt skilda levnadsförhållanden har flera hundra olika raser utvecklats, vilka skiljer sig bland annat vad beträffar ull, storlek o fettdeponering. I Sverige ökar produktionen av lamm året runt, vilket innebär att lamning sker även under de kallaste vintermånaderna. Detta skulle kunna innebära problem då lammen kan ha svårt att hålla sin kroppstemperatur vilket påverkar överlevnaden. Insatser som kan göras för att förbättra lammens chanser är att utfodra tackan väl, klippa tackan några veckor före lamningen, se till att tackan slickar sitt lamm torrt och försäkra sig om att lammet har god tillgång på mjölk.

Ny huvöppningslösning för Eco-Logs skördare : Från idé till tillverkningsunderlag

Hårdfräsning i verktygsstål : Förslitning av skäregg

This thesis work is made by Torbjörn Johansson on Karlstad University for Uddeholms AB. The assignment in this thesis work was to investigate tough cutting in three different tool steels: Vanadis 4 Extra, Vancron 40 and Sverker 21. The research was to compare the wear of the tool after cutting in each one of the tool steel alloys. The research was also made to see if the tool cutting in Vancron 40 has a better wear than the tool cutting in Vanadis 4 Extra and also compare the results with Sverker 21. All three of these alloys are a part of Uddeholms AB:s range of products, and is used in applications like forming tools and knife tools. Vancron 40 is a powder steel with a very good combination of mechanical properties like ductility, adhesive strength and hardness.

AimThe specific questions in the theoretic part were:What is contained in the terms "balance and balance skill" and how can this skill be measured?The specific questions in the empirical part were:How does balance skill in different age categories of children correlate with biological and physiological parameters such as age, gender, body height, weight and level of physical activity?MethodsLiterature search based on books and scientific papers related to the questions posed above. Selection was made at libraries and on?line through "Pubmed". Specific search words were used.

Robotinteraktion på litet företag : Examensarbete Industriautomation

The division of Electricity at Uppsala University runs a project called Lysekil project, they have designed a buoy that uses the waves to create electric power from a generator attached to the bottom of the sea.Uppsala University is closely connected with the company Seabased and the university makes use of their facilities in Lysekil. When they designed the buoy issues occurred, the geometric design was flawed, brackets with a short shelf life and it is generally uneconomic.A study visit was done in Lysekil on Seabased facility. With this visit the project started, which is to improve the design of the buoy and the attachment of wires leading to the generator. In this project we have chosen to use a beam system with three beams that are attached to the buoy. Then a wire attached to a plate that sits between the beams will be leading to the generator. Two proposals for construction are created, what distinguishes them are the brackets between the beams and the buoy.From these constructions, the design that is considered most optimal for our project is chosen.All parts of the buoy have been modeled and the drawings are designed in ProEngineer software.The two constructions are compared with each other, but the whole focus is on the second and final structure. The report begins with an introduction describing Lysekil project, and a task description of our project.The project aims to produce an optimal buoy that will be easy to design, materials restrictive with good durability and an economical solution.Wave power true function has been studied, mechanical and finite element analysis of beams, buoy and plate design.This has been presented in this report, where in the various chapters can read more about the processes. Although the relevant facts and information on this project and buoy development is included.

Ändrad användning av stationshus : fallet Ormaryds station ? ett stationshus med betydande kulturvärden

Acquiring a former station building can mean that the property owners must familiarize themselves with a lot of planning and building regulations. After the new Planning and Building Act code into force in 2011, the responsibility lie on the developer to ensure laws and regulations. Based on the regulatory framework that is available occurs sometimes balance issues, between care requirements and building codes. The station building in Ormaryd was acquired in 2009 by two individuals who intended to accommodate office and retail space in the building. In doing so a new local plan of the area was established, including regulations on how the building could be used. By including road safety and noise, the risk was not considered appropriate to use the station building for housing.

Utformningen av ett förstärkt skruvförband på en differentialväxel i bandvagnen BvS10 : Analys av olika förband med hjälp av CATIA och MATLAB

This is a thesis presents a differential gear which is found in a tracked vehicle called BvS10. The tracked vehicle is manufactured by BAE Systems Hägglunds AB in Örnsköldsvik, Sweden. The differential gear has a bolted house. The differential meets the requirement specifications, but the problem is that the bolts are sheared off because of the extreme torque that the differential is exposed to resist.Previous report on the differential show pictures of bolts which have been sheared off at the threads. This report is also includes three lists that explain seven different proposals which some are approved and some are not, and the report also presents the force, tensile, and shear stress.In a bolted connection there is both axial tension stress and radial shear stress, which can lead to wear out and broken bolts.

Passivhus - studie om miljövänliga och energisnåla bostäder

Detta examensarbete syftar till att försöka redogöra för möjligheten att minska energiförbrukningen för bostäder i Sverige. Idag står bostadssektorn för cirka 40 % av landets totala energianvändning. En satsning på lågenergihus såsom passivhus kan därför komma att ha stor betydelse för Sveriges strävan mot en hållbar utveckling när det gäller energianvändningen. Det är inte bara miljön som gynnas av energieffektiva satsningar utan även den boendes egen ekonomi. Detta eftersom framtidens energipriser sannolikt kommer att vara kraftigt stigande.

Kalkonproduktion i fårstall : synergieffekter

Målet för det här projektet är att se huruvida lönsamheten inom fårproduktionen kan förbättras genom ett högre utnyttjande av fårstallet. Det görs genom att bedriva omgångsvis uppfödning av kalkoner i halva ?fårstallet? under sommarhalvåret. I den här studien har jag utgått ifrån att köpa fem veckor gamla kalkonkycklingar till produktionen istället för att köpa dagsgamla kycklingarna vilket är det vanliga. De dagsgamla kycklingarna är känsliga och kräver mycket av både stallmiljö och djurskötare.
