Modellering och reglering av drivenheter i gaffeltruck

To enable the enhancement of the driver's environment in a forklift, an alternative form of steering has been evaluated. An earlier concept with a combined driving and Steering wheel has been exchanged to a concept with two driving wheels. A link wheel has replaced the combined driving and Steering wheel. The steering is done through differentiation of the velocities of the two driving wheels. The scope of this master thesis is to create a simulation model, create a control program and to evaluate the concept of two driving wheels.

Konceptuell design och utveckling av hybridfordon

This report covers the conceptual design of a new one person hybrid vehicle that is to be fast and convenient to drive on the roads. The vehicle is most of all supposed to be used as a commute vehicle but can also be used at other occasions as well.During the work with this project the group has focused on three larger areas, the outer design (body), wheel chassis and an ergonomically designed interior. The group was not able to just create these parts in 3D to get a trustworthy vehicle, hence number of other components and details were also created to get a better entirety.The outer design starts with idea generation and sketches and ends with a 3D model which is rendered to show how the final product is going to look. The design of the body has been going on during the entire work process due to new ideas and improvements that seemed interesting and had to be changed.The wheel chassis also started with idea generation, research and sketches. It ended up with a simulated 3D model which later on was mounted on the vehicle body to show how the vehicle is going to perform during usage.

Konceptstudie av eltransmission för 8-hjulsdrivet fordon

SEP Modular Armoured Tactical System is the next generation of military vehicles developedby BAE Systems Hägglunds AB. At present time, BAE Systems Hägglunds AB aredeveloping a 6-wheel electrical hybrid and a conventional 8-wheel vehicle. The questionformulation was summarized as: ?In which ways can the electrical transmission in a hybriddriveline for SEP be designed, when the surrounding fixed interfaces are kept and the unity ofcomponents within SEP is maximized??. The purpose of this master thesis was to study avariety of concepts for hybrid propulsion.

Styrtransmission för bandfordon

The purpose of this master thesis is to construct a steering transmission, for a trackedvehicle, containing two hydraulic circuits which are connected. The steeringtransmission should be mechanical to avoid steer-by-wire.BAE Systems Hägglunds has in an earlier study examined a system with two hydraulicpumps and one hydraulic motor, but the safety of the system wasn?t sufficient.To achieve sufficient redundancy there must be two hydraulic motors, which arecontrolled separately. When the two systems are connected in one point, this point is acritical part of the system because it directly affects both circuits. If one of the hydrauliccircuits fails the other should be able to operate independently as a steeringtransmission.

Reducering av en komplex produktstruktur : - En studie av bränsletanksinstallationen på Scanias lastbilschassier

The product structure of the fuel tank installation is one of the most complex product areas at Scania. Caused by the number of parameters, which affect the fuel tank installation, a product structure is created which is very difficult to handle. Knowledge exist that the structure in a nearby future will be considerable more complex. The purpose of the study has been to understand in why this complexity exist and find ways to break the trend of a growing product structure. The goal was to achieve a more standardized fuel tank installation.A theoretical study was performed in order to bring knowledge in relevant areas both in general theory but also in documentation at Scania.

Diagnostiksystem i gaffeltruckar

This is a final thesis done at BT, considering one of their forklift truck models called Reflex. The first part of this report is about a preliminary investigation investigating what kind of diagnostic systems BTwants to use, and also which demands there are to meet all expectations on such system. Secondly a diagnostic system, which will show if the drive wheel is worn out, will be presented. In the preliminary investigation, two kinds of diagnostic systems were mentioned. These were Model based diagnosis and Predictive analysis.

Svensk asylpolitik : En studie kring styrning och långa handläggningstider på Migrationsverket

The Swedish Migration Board has during a long time had problems with long processing times for persons that apply for asylum. The government has set targets that investigation should not exceed 6 months although it is done in almost 70% of cases.The study's aim has been to examine if steering can be linked together to long processing times and, if so, explain why. The intention has not been to provide a comprehensive picture of the problem but has defined itself to ensure steering impact. The study has been carried out by studying relevant governing documents, previous research and by interviews with administrators and decision-makers in two of the Migration Board asylum units.The analyses of the study show that a combination of inadequate steering and inadequate resources have contributed to aggravate the implementation, which has lead to long processing times..

Verktyg för hjulbyte

Purpose of the thesis is to construct a tool for car wheel change. Car wheels can be heavy and hard to handle and therefore the company Movomech intends to develop a tool that makes wheel change easier. Movomech does not have any similar product and because of this the work was condition less.The intended users of the product is tire workshops and there for the work began with investigation of these. The reason of the investigation was to see how wheel change is done and how tire workshops are planed. The tire workshops? crew?s opinions were also considered and above all one important conclusion was made.

"Biblioteken ser vi som en positiv verksamhet" - en studie om styrning av folkbibliotek i fem svenska kommuner

The aim of this study is to explain and analyse political steering of public libraries in Swedish municipalities and the roles of politicians and administrators in this process. To fulfil this purpose five municipalities have been studied. It is argued that both politicians and administration have to be included in a study of steering and that the relation between politicians and administrators should be seen as an interplay. Planning and evaluation are discerned as the two main activities in the steering process. The material in this study consists mainly of information collected through interviews with library responsible politicians and library managers in all five municipalities.The results show that libraries are considered politically uncontroversial and that politicians see little need for political interference and steering.

Konstruktion och design av hjul

The task given to us was to develop an industrial wheel with new thinking in terms of fresh design and construction, with the ability to brake. While the produced wheels of today only own the property of total braking, a wish was made to integrate the ability of directional locking.The time spent working with the project has been filled with multiple sketches of ideas and function analysis.Choices of material and ways of construction have been verified by calculations, tests and prototype building. The goal of this thesis has been to develop a unique caster with well thought-out design that would be adaptable to different areas of applications.The result was a hubless wheel with the ability of directional locking before total braking.A prototype of the wheel has been made to show the design and functions..

Vad skola vi göra med litteraturen? : En studie av de nya styrdokumenten samt ett urval av läromedel och deras föreställningar om och legitimeringar av skönlitteratur i det svenska skolsystemet.

In this thesis I set out to study how the reading of fictional literature is viewed, legitimatized and operationalized in two educational domains: the recently revised steering documents that all Swedish teachers must relate to, as well as a selection of teaching materials designed for education in the Swedish language for upper secondary school. The teaching material I have studied has been recently updated in order to correspond with the new steering documents. I relate my analysis to previous research about the use of fiction in education, and I also combine my analysis of the two educational domains to see whether the underlying intentions of the steering documents have influenced the revision of the teaching material. The outcome indicates that the steering documents? previous focus on culture has diminished although a certain insecurity as to how to use the concept and deal with the issue of whose culture should be taught can be identified.

This report is a bachelor thesis work within the field of Product Development and is also an assignment for Thule Sweden. The work has been performed by Niclas Tjäderborn and Christian Holm, students at the Mechanical Engineering Program with major in Product Development and Industrial Design at Jönköping School of Engineering during spring the semester of 2009.The thesis work concerned the development of a new wheel holder for bike carrier for Thule Sweden. The background to the project was that the initiator wanted a more user friendly wheel holder with better design than those available on the market. The wheel holder is able to be implemented on one or several of Thule?s current wheel holders.

FE-modellering av hjullast på sandwichpanel

This bachelor thesis in mechanical engineering was performed during the spring2015 in collaboration with Composite Consulting Group in Laholm. TheComposites Consulting Group works mainly with design and details of differentcomposite projects, their main area is FE-calculations, 3D-modelling andmechanical tests with composite materials.The aim of this bachelor thesis was to simplify the calculation process of solidmechanics for sandwich panels by simulation with computer software. The goalwas to decrease the time for the design and calculation process of the constructionand the cost of the practical tests. Our task was to build a static three dimensionalmodel with the computer software Abaqus, where the result should correspondwith the practical pressure tests in laboratory.The project started with collection of material data from Composites ConsultingGroup and by learning the software Abaqus, simultaneously a specification wasdeveloped in corporation with the company. Later on, a static wheel pressuremodel in the software Abaqus was produced which simulated the behavior of thesandwich panel during static wheel-pressure by a pallet truck.
