Problem descrip-tion: Design codes today are generally based on simplified hand-book calculations, which cause problems with the application of FEM. There are no recommendations in the design codes on how FEM shall be applied when performing fatigue life analysis of welded joints. The difficulty lies in how the results shall be interpreted. Objective: The objective with this project is to establis

Sealings are an important part in the industrial robot. One important property of the seal is to keep all particles and fluids from the outside, away from the important components inside the robot. Another important property is to keep the oil and grease inside the robot, and prevent leakage. The seal also prevent leakage inside the industrial robot and reduces the risks of sensitive components to

Texo AB is a private company which is specialized on development of looms for production of paper machine clothing. The company is located to Älmhult in southern Sweden and today employs about 90 persons. The calculation job treats 4 independent tasks, of which 3 is dealing with the same type of machine which is almost at the prototype state at the moment. The new machine TC 74 is a cam controlled

This Master Thesis has been completed at the research and development department of Sandvik Mining and Construction in Perth, Australia. The scope of it, specified by Sandvik, includes two main task, both part of greater product development processes at Sandvik Mining and Construction. The first task is an incremental improvement of an existing product. Sandvik believes their patented Dual Propert

The production of core material/blocks is divided in multiple steps. Before the hardening process the blocks are placed horizontally in stacks of 10 on a pallet. Between each block plastic spacers are placed to insure a spacing of 5 – 8 mm in between the blocks. This is done to achieve a better water flow and cooling efficiency in the hardening chamber. The use of plastic spacers complicates work

This master thesis explores the usage of stainless steel in mobile phones. The first part is an introduction to stainless steel which explains the properties of the different stainless steels, and also the most common methods used for sheet metal production. It is concluded with a selection process to determine which stainless steels are best suited to be used at Sony Ericsson Mobile Communication

Discussion The trend on the mobile phone market indicates that mobiles with advanced texture will be in demand. Sony Ericsson Mobile Communications AB would like to examine what possibilities there are in the field for texturing. In 2006 they introduced the mobile phone W850i with advanced texture on the market and now they want to know more about different techniques for texturing in the future.

NIMCO Controls AB is a company located in Malmö, Sweden, that manufactures hydraulic valves mainly for the farming industry. They proposed me to work on three independent design projects to renew their product range. The first topic was a platform research for handgrips. As the company uses lots of different lever systems that need a handle, the main objective was to design a platform which deriva

The removal of snow and ice from aircraft prior to take-off is a major task at all airports located in cold climates. Currently the removal of ice and snow is carried out using large amounts of costly and environmentally harmful glycol that is sprayed onto the outer surface of the aircraft. Tougher environmental regulations and a cost conscious market have created a growing need for alternative me

Background The telecommunication market is characterized by short product life cycles why the time of the development process has to be minimized. This means lack of time in the development process why known and tried design solutions are being used to a great extent instead of trying new and less conventional solutions. The market is also striving to minimize the size of the mobile phone while in

The background to this master thesis is that various studies show that the milk consumption in Swedish schools is decreasing. Offering flavored milk will hopefully make milk more attractive. The concept with flavored milk has previously been tested in a prestudy where a rig were made to test the basic idea. There is now an interest in taking the project to the next level by building a prototype. T

The purpose of this thesis was to develop and design a new machine for fatigue testing of bicycles. It was carried out for and in close cooperation with Svensk Maskinprovning AB, The Swedish Machinery Testing Institute. The machine was to test certain bicycle components according to a new standard of certification, valid in the entire EU. The goal was to attack the problem as openmindedly as possi

AB Ph. Nederman manufactures capture at source extractors that remove dust and fumes from a specific area. These extractors are made of a positioning joint which has the purpose to hold up the extractors’ hood. Presently this joint is made of a double ball joint; this doesn’t however work in a satisfying way. First and foremost it is hard to move the joint when repositioning the hood; this is not

Interpretations of the term Corporate Social Responsibility are many, but academics have achieved approximate consensus about what it consists of. An issue that started off as an interest- and motive-based activity for businesses is becoming more commonplace and has increased in importance over time. Governments have a role to play in ensuring that corporations behave according to the rules and no

Abstract This is a diploma work in industrial design by Fredrik Hyltén-Cavallius. In this project my goal was to find a product that could make the ancient fire fit better into our modern homes. I started out by looking at fire related products such as stoves and barbecues on the Swedish market. Through several interviews I also looked more closely into a couple of heat related technologies such a

This study looks into the existing policy gap in the management of E-waste in the Philippines, by identifying the different barriers to – and drivers for – the adoption of E-waste management measures, through the perceptions of the different stakeholders involved in E-waste issues. Existing waste management policies in the country lack a specific framework for dealing with E-waste. This research e

The traditional approach of dealing with transportation issues appears to be insufficient in bringing about sustainable urban traffic, as it does not take into account complex psychological processes assisting people in making their travel choices. New approaches are required to raise the effectiveness of transportation policies, by facilitating higher levels of public acceptance and engagement in

In India, emissions of greenhouse gases (GHGs) are increasing, due to the rise in energy demands to sustain economic growth. Coal is used as a dominant fuel in Indian thermal power plants, but the efficiency of these is low in comparison with prevailing international standards. As such, emissions of GHGs are much higher than is feasible to achieve. The adoption of Clean Coal Technologies (CCTs) –

Access to electricity is important to meet the Millennium Development Goals (MDGs). The centralized model of large thermal power stations and a central grid is a conventional system to supply electricity to consumers. This centralized model has failed to provide electricity and to achieve the rural electrification objective in developing countries. Un-electrified areas of the developing world are

This research investigates the current situation of bioenergy development in rural China from the business perspective. Biomass combustion power stations, medium and large biogas facilities, and household level biogas digesters are discussed in the research. In total 6 empirical case studies and interviews with different stakeholders are employed in the research. This thesis argues that the govern
