  1. 21. Parametric Studies of Soil-Steel Composite Bridges for Dynamic Loads, a Frequency Domain Approach using 3D Finite Element Modelling

    University essay from KTH/Bro- och stålbyggnad

    Author : Jonathan Ljung; [2019]
    Keywords : dynamics; soil-steel composite bridges; corrugated steel plates; frequency response functions; frequency domain; perfectly matched layers; Comsol Multiphysics; parametric studies i;

    Abstract : In this thesis, parametric studies have been performed for a soil-steel compositebridge to determine and investigate the most influential parameters on the dynamicresponse.High-speed railways are currently being planned in Sweden by the Swedish TransportAdministration with train speeds up to 320 km/h.

  3. 22. Investigation of wear behavior of different sliding bearing materials in an alkaline environment

    University essay from

    Author : Martina Ottosson; [2018]
    Keywords : wear; tribology; alkaline; sliding bearing;

    Abstract : In sliding bearing wear is a very common problem and can be affected by several factors. The wear in a bearing can lead to total failure of the component and lower the lifetime. In a sliding bearing used in a machine in the pulp and paper industry large wear has been detected, but no clear evidence of what the wear depends on. READ MORE

  4. 23. Algorithms for Mold Temperature Detection and System Investigation

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Boying Li; [2018]
    Keywords : Continuous casting; OptiMold Monitor; high-resolution measurements; online detection; algorithm; Kontinuerlig gjutning; OptiMold Monitor; högupplösta mätningar; realtidsupptäckt; algoritm;

    Abstract : Recently ABB AB/Metallurgy has developed a novel temperature measuring system in the mold copper plate for continuous casting, named OptiMold Monitor, with the purpose of dynamically monitoring mold conditions and to control the FC Mold.The OptiMold Monitor temperature signals can be further analyzed for the information of the shape of the meniscus of the molten steel together with fluid flow symmetry and speed.

  5. 24. A digital image correlation method for detection of fatigue cracks in non-load carrying T-joints

    University essay from KTH/Lättkonstruktioner

    Author : Björn Jonsson; [2018]
    Keywords : ;

    Abstract : In dynamical loaded welded structures fatigue life is often a limiting factor. Common practise is to reduce nominal stress by increased material thickness which leads to oversized, heavy structures. Those practises are replaced by improvement of production and designingtechniques to utilize better properties of high strength steels. READ MORE

  6. 25. Lubricants impact on cutting forces - Torque reduction in tapping process

    University essay from KTH/Industriell produktion

    Author : Marco MANGIATERRA; [2018]
    Keywords : Lubricant; Broaching; Cutting Fluid; Tapping; Torque; Smörjning; brotschning; skärvätskor; tappning; vridmoment;

    Abstract : Bearbetningsprocesser är en viktig del av tillverkningsindustrin. Dessa företag måste kontinuerligt förbättra sina processer och göra dem mer effektiva, minska de ekologiska fotavtrycken och driftskostnaderna. Syftet med denna rapport är att förbättra en rund brotschningsprocess för ett bilföretag. READ MORE
