<em>Ett modernt dimensioneringsproblem för huskonstruktörer</em>
… to human activities. Floor-systems, consisting of concrete slabs supported by steel or concrete beams, have been investigated with simulations in the finite element program Abaqus. In the simulations, the influence of various factors on the natural frequency of floor-systems and …
… made to fit the combinations between tipper and dumper as well as aluminum and steel hatch. The hinges are similar to each other and only a few details separate them. All components in the door hinge are adjusted for the production at Zetterbergs. The door hinge is designed in a …
Fördelar ur kostnads- och miljösynpunkt vid användning av rostfritt stål och direktgjuten betong
En stor del av Trafikverkets budget går till att reparera och underhålla våra broar. Underhållsåtgärder orsakar också trafikproblem med stora miljöutsläpp och samhällskonsekvenser som följd. Eftersom broar vanligtvis dimensioneras för en lång livslängd på 120 år är det viktigt …
… fiber, for example costs andincreased demands on work environment, which makes steel a cheaper option.
Produktutvecklingsprojekt för en effektivare och mer användarcentrerad metod för tillskärning av nätisoleringsmattor
… installations. The insulation consists of stoneor glass wool with a sewn on steel wire netting on the out facing side. This netting has thepurpose to enable fastening to e.g. ventilation ducts and to provide bounding of joints. Thiswire netting makes regular methods for fitting …
En studie av Sandvik Coromants försörjning av stål
… The report aims to give suggestions to improvement areas within the buying of steel. Subjects covered are order procedures, material handling, stock and quality of the purchased material. The study covers four manufacturing groups within the production facility. The suggestions …
… work is about the development of a concept for the skidbeam where steel is replaced by a composite material. Due to lack of knowledge about fiber composite and their manufacturing processes, a pre-study was made. After the pre-study the concept work on the beam was initiated …
… to absorb compressive forces and on the underside of the element a sheet of steel is added for tensile absorption. These elements are then attached to the building framework in different ways depending on the particular element height, loads and the structual supporting material …
A preliminary study
… oxidation is currently being used on the tool holders made of low alloyed tool steel produced by Sandvik Coromant. Black oxidation isn’t considered a sufficient technique because it doesn’t make the tool holders look like the quality products that they actually are. The …
Optimerat materialutnyttjande i byggnadsstommar
I detta examensarbete utförs en jämförelse av HSQ-balkar och VKR- pelare i hållfasthetsklass S355 respektive S460. I arbetet dimensioneras profiler anpassade efter studerade fiktiva konstruktioner och ställs emot varandra. Syftet är att optimera profilerna och effektivisera …
Klarläggande av framtida hållbarhet
… be done, in particular new materials are needed because hydrogen embrittles steel. Hydrogen is stored either as a liquid or as a compressed gas. Liquid hydrogen stores more energy on board by volume relatively compressed hydrogen, but must be cooled to -253° C. When the vehicle …
… future. The most prominent competitive advantages for glulam, in comparison to steel and concrete, are the environmental aspect and the experience for the end user. Toughest competition concerns construction technology aspects.
En intervju och enkätstudie i Halmstads kommun
