Rekursiv greyboxidentifiering av drivsystem i industrirobot.

Magisteruppsats · Linköpings universitet

… in an industrial robot. The nonlinearities that are identified are friction, spring stiffnes, hysteresis and backlash. These nonlinearities are a part of the models that are presented in this thesis. Apart from models there is a need for some sort of algorithm for the …

Ultraljudssvetsning

ett komplement eller ersättning till symaskinen?

C-uppsats · Högskolan i Borås · 2007

… were performed. Ultra sonic welding is a technique which generates inner friction inside the material when it is exposed to pressure. The inner friction creates heat which melts the material and bonds it together. The bond needs time to stabilize before the product can be used …

Studie av nötnings- och friktionsegenskaper vid höga temperaturer i Kanthal APMT

Examensarbete, avancerad nivå · Uppsala universitet

During this master thesis, wear and friction properties for the high-temperature alloy Kanthal APMT were studied. The results were also compared to 253MA. The initial tests showed, among other things, that the surface fineness of the muffle tubes matters in real applications …

Formulering och provning av en ny typ av sågkedjeolja

Examensarbete, avancerad nivå · Uppsala universitet

… developed to investigate the wear. Not only wear has been studied, but also friction and the ability of the lubricant to stay in the system without new being applied. Three new lubricants have been tested. Most chainsaw lubricants on the market are based on either mineral oil or …

En studie om samarbetet mellan socialtjänst och polis

Examensarbete, avancerad nivå · Karlstads universitet

… the others involved are. However, this very co-operation can sometimes cause friction, because of the fact that the police and the social services do not always get the same picture of the youth that they are working with. This is because both agencies get to see the youth in …

Fallstudie av produktionschefers ledarskap

Högskoleuppsats · Högskolan i Halmstad

… In the present bogie system the main problem for a proper function is the frictional forces that appears in the surface between the spring and the spring seat. In the report a proposition with a rubber part between the spring and the spring seat is introduced, with the idea to …

Matarverk för Camcoil

C-uppsats · Karlstads universitet

… a strip feeder consists of two rollers which with the aid of the friction between the strip and the coating on the roller create a strip force that pulls the strip through the working progress.Demands on this project:? 10 ” 600 mm in strip width and 0,1-1 mm in strip thickness.” …

Naturlig haptisk kraftåterkoppling från volymdata

Examensarbete, grundnivå · Linköpings universitet

… volume visualisation environment. To achieve the feeling of stiffness and friction dependent on tissue type, a proxy based method was developed. In the volume the proxy is constrained by virtual surfaces defined by the local gradient. This algorithm was implemented in a volume …

Diagnostiksystem i gaffeltruckar

Examensarbete, grundnivå · Linköpings universitet

… varying diameter of the drive wheel, varying load on the truck and varying friction in the gearbox. Using hypothesis tests, it is possible to say whether the drive wheel is worn out or not. Results show that if the drive wheel diameter is reduced by 25 mm, torque is reduced by …
