a comparative study of piglets reared on structured polyurethane coating and piglets reared on concrete floors
… floor in farrowing pens, as it must suit both the sow and piglets. The floor friction needs to be adequate to avoid slips and at the same time should the floor be non-abrasive. Abrasions and lesions caused by the floor are not only causing the animal suffering, but are also …
En analys av medeltida konstruktionsråd för mekaniskt artilleri
… by Jahsman (2004). A more detailed mathematical model employing Coulomb-friction is used. The dimensioning of the arm and the analysis of the loads are more detailed in order to give the arm more representative qualities and in order to easier notice deficiencies in the selected …
… To do that, axial force will be used to press the bearing against a high friction shim fitted between the bearing and the shaft. The friction shim is made of a thin steel foil with diamond particles fixed in a nickel matrix on both sides. The thesis evaluates several questions …
Piled friction soil show a set-up which is increasing with the time after installation. The cost could be reduced if the set-up had been taken into account when designing but in Sweden it is very unusual to do that. Previous studies showed that set-up can vary between 25 % and …
Fallstudie på länsväg 360 Lycksele - Vilhelmina
… from occurring. The road parameters chosen for this study include side friction, cross slope and rut bottom cross slope, road texture, curvature, drainage gradient and rutting. The case study was limited to lv 360 in Va?sterbotten, where all accidents with an unclear cause of …
… products there exists some concern regarding the amount of clamping force and friction on bolted joints caused by the assembly torque. The aim of this project has been to determine if there is a simple way in which to identify and then practically apply testing methods for …
Jämförande sonderingar och utvärdering av egenskaper i isälvsavlagringar kring Igelstaviken
… the soil parameters for the Total sounding method (TS), such as the inner friction angles and settlement modules. This study only includes an analysis of soil profiles from the Stockholm region. The chosen location for the study is a proposed residential area east of …
En studie i curlingens komplexa tribosystem
… scanning interferometry, it has been decided that the curl is not due to dry friction, ice-debris or the difference in friction on the left and right side of the stone. The side force comes from the fact that the friction is higher at the back of the stone than at the front.The …
… liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved. The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and …
Med avseende på friktion och nötningsmotstånd
… liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved. The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and …
… against a hard anodized joint ball. Despite the fact that the plastic contain friction-lowering additives, the bearing needs to be lubricated to prevent noise. Because the robot is used in food and drug handling environments, where the demands on hygiene are set very high, the …
… with cold rolling of an aluminium strip have given results for rolling force, friction, reduction, strip tension and strain hardening. Results show that steady state has been found for the experiments with roll force and strain hardening, and not been found for the experiments …
Reaktorinneslutningen på Forsmark 3
… ring-shaped part of the nuclearcontainment vessel. The results from the first, frictionless, model agree with similarsimulations and hand calculations for high pressures in the containment vessel. Thesimulations of the nuclear containment vessel show cracking in the concrete …
… showed that the probable cause of instability is a decrease of the viscous friction, which gives worse damping characteristics. It was more suitable to base the controller parameters on the valve opening instead of the working point for the robot arm, since the gain in the valve …
… not keep its speed with maximum use of fuel. A conclusion was stated that the friction and height profile influenced on settings for the PI-regulator and with some adjustments on this settings, fuel could be saved.
