Parallel kinematik machines are nowadays an important branch of investigation in the robotics field. Its design allows for high speeds, accelerations and tool forces as well as makes them ideals for faster cycle times and high repeatability works. TAU is a parallel kinematic machine from ABB Company with three degrees of freedom. Therefore, it can be positioned anywhere of the workspace but not or
The goal of this thesis was to design a Multiple Hull Valve (MHV) with the purpose to increase the safety and decrease the amount of hull penetrations in a submarine. The safety is improved by a double shut of function where the outer plate valve is closed by the pressure difference in case of failure. A great advantage with the MHV is that the systems in an early stage are protected from both mar
This report is a result of a Master Thesis made at Volvo 3P and the Department of Advance Engineering and Concepts. The thesis is a part of the education in Mechanical Engineering at the Department Design Sciences, for the Division of Machine Design at Lund University. Volvo 3P is involved in a project regarding a new patented manufacturing method that is under development. The manufacturing metho
The goal of this project was to create a banknote deposit machine or Cash Deposit Machine (CDM) for Retail Cash Systems (RCS) at SCAN COIN AB in Malmö. The CDS was to be based on the currency counter SC1510 Euro Value. The idea was, since the technology was already there, in the SC1510 E V, to put it in a box and, with all transport and storage inside solved, a CDS would have seen the light. I wan
This Master Thesis has been performed as a development project for Asko Cylinda AB in Vara, Sweden. The company develops, manufactures and markets conventional tumble dryers among many other products. An important part of a tumble dryer is the filter holder with belonging fuzz filters mounted on the door of tumble dryer’s. The fuzz filter’s objective is to filtrate the hot drying air that pass thr
This project was done for the company Beijer Electronics Products AB and the task was given by the hardware development department of the company. The project was about developing a concept proposal for a new generation operator panels. This was done to inspire the product developers at Beijer Electronics with innovative ideas before the actual operator panel development. More in detail the object
The aim of the thesis was to help Tetra Pak with problems that have occurred with the creasing-unit. This unit is one of great importance in the production line for a final package with good quality. The unit is built up in modules, where each module performs the wanted operation. The motion between and in the modules is transferred by a gear transmission. The quality of the packages is decided by
This Master Thesis, performed at the Division of Machine Design at the Faculty of Engineering , Lund University, and at Zenit Design Group AB in Malmö. Zenit Design is one of Sweden’s leading design studios. Zenit Design has received the assignment from Blueshift Solution. The Master Thesis was going to result in a first stage prototype of a handheld game console and a 3-d model made in CAD. Also
This thesis is conducted in collaboration with Alfa Laval Lund AB. Alfa Laval is a world leading producer of heat transfer, separation and fluid handling equipment. The products help Alfa Laval’s customers to heat, cool, separate and transfer products such as oil, water, chemicals, beverages, starch and pharmaceuticals in over 100 countries all over the world. The hardening competition together wi
The focus of company’s aftermarket is no longer only the “machine shop” where aftermarket finds solutions to offer spare parts to the customers. Instead aftermarket is focused on technological improvements that continue to change and improve on the way aftermarket operates. The way aftermarket operates has shifted from reading documents to be more integrated with computers and the next step is, fo
This paper examines the effect of various factors on the commuting behaviour of one- and two- worker households. The households' choices in the land- and labour markets are modeled in the context of Becker's common-preference framework. The empirical investigation using data from the 2007 American Community Survey also tests the Household Responsibility Hypothesis. I find that women have s
The aim of the present study was to examine the electrophysiological correlates of semantic generation, to study how repeated semantic generation, repeated study and repeated test opportunities affect memory performance and to create a non-verbal Stroop task. Earlier research has showed that cued semantic generation, also referred to as word generation, can cause forgetting of other memories assoc
"What should we have for dinner?" is one of the most challenging and anxiety provoking questions of today. In a society where appreciation for eating rituals and common knowledge about food have been almost lost, a new look at layout, space and functions of kitchens is needed to demystify and dedramatize the dogmatic image people have of cooking so they can rediscover the fun in the kitc
Syfte: Syftet med vår uppsats är att ta reda på hur och på vilka sätt Generation Y (80-talisten) agerar med sina gemenskaper på den virtuella mötesplatsen Facebook. Metod: Uppsatsen är av kvalitativ karaktär och bygger på en metod som kallas fokusgrupp. Målet med fokusgrupper är att deltagarnas åsikter ska komma till tals och diskussionerna utgår från deltagarnas erfarenheter av ett specifikt ämn
According to research from the Municipality of Lund, our travel habits as adults are to 90 percent obtained before the age of 13. Yet, every 4th child in Sweden is given a lift by car to school and day nursery often less than 1000 metres away. These short journeys could easily be replaced by bike. By constantly choosing the car, we adults pass on the attitude of the car being the mean of transport
This paper aims to dig into the world of trucking and finding new possible solutions to the problems of pollution. The project focused on the exterior features of the modern truck with the goal of combining aestethics and technology into a more functioning and desired design. Research involved interviewing people involved within the business, particularly drivers in order to find problem areas fro
The bike helmet is certainly a topic of current interest. From January the 1st 2005 it is mandated by law that children under 15 years old must use bike helmet when biking or being given a lift on a bike. There is an ongoing debate about the next step, to develop the law on bike helmet to apply for adult bicyclists as well. If a law like this would be established, the request on bike helmets would
My diploma work is a design of a "walk behind" concept. The concept is an "all season outdoor product". The idea is to give a first time house owner a product that can do the mayor chores in the yard during the different seasons. It is 3 products in one. It's a lawn mower, a snow thrower and a power brush. I attacked the design of the product from 3 different angles. From
