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 …
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 …
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 …
… forskning om våta kopplingar som involverar pappersbaserade friktionsmaterial. De två vanligast förekommande materialen i produktion, i detta examensarbete benämnda som material A och B, testades i en testrigg på LTU. Material A visade upp ett nötningsfenomen där …
… properties. The parameters of the textile material would meet was to hold high friction, wear resistance, adhesive while being environmentally friendly. Background material was presented and a set of requirements and concepts that were evaluated. The concept that received the …
ett komplement eller ersättning till symaskinen?
… 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 …
… 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.” …
<em>Modell för jämförelse av vägöverbyggnader med eller utan geotextiler och/eller geonät</em>
… reducedFilling material density has increased due to geogrid wedging mechanismFrictional resistance has increased due to the fact that pavement materialparticles have been extended due to geogrid’s wedging mechanismSuperstructure’s total thickness has been reduced due …
… amusing features inside. Thanks to Boleko concepts such as energy, magnetism, friction, gravity, light reflection, mathematics and mechanics become real in an inspiring way and stimulate interest in science and technology. Children of different ages with different backgrounds …
… it can be seen just on the seals? A rig test was conducted where we show how friction, speed, transmission temperature and mitigation phases of the retarder affects temperatures in the sealing environment. Factors affecting the coke structure are reported, together with …
… mostly about superhydrofobic surfaces, since the production of totally frictionless surfaces is not yet a possibility. There are different ways to create the so called Lotus effect with superhydrophobicity on a surface. One way is to start with a material with low surface energy …
The aim of this thesis was to investigate if the robotized welding method FSW (Friction Stir Welding) could be applied for joining a rotating structure in an aero engine at Volvo Aero Corporation. FSW is expected to introduce less defects than today’s welding methods and could …
