  1. 21. A Geometallurgical Forecast Modelfor Predicting Concentrate Quality in WLIMS Process for Leveäniemi Ore

    University essay from Luleå tekniska universitet/Mineralteknik och metallurgi

    Author : Kartikay Singh; [2017]
    Keywords : Mineral processing; geometallurgy; modelling; Davis Tube; WLIMS; LKAB; Leveäniemi;

    Abstract : Previous studies have suggested that Davis tube (DT) experiment can used to study wet low intensitymagnetic separation (WLIMS) for magnetic iron ores. But DT process has never been used to mapWLIMS process, specifically in a geometallurgical framework. READ MORE

  3. 22. Modal analysis of pedestrian-induced torsional vibrations based on validated FE models

    University essay from KTH/Bro- och stålbyggnad

    Author : Simon Chamoun; Marwan Trabulsi; [2017]
    Keywords : Modal analysis; validated FE models; pedestrian-induced vibrations;

    Abstract : Finite element (FE) models serve as the base of many different types of analysis as e.g. dynamic analysis. Hence, obtaining FE models that represent the actual behaviour of real structures with great accuracy is of great importance. READ MORE

  4. 23. Evaluate Operational Modal Analysis and Compare the Result to Visualized Mode Shapes

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Baiyi Song; [2017]
    Keywords : Operational Modal Analysis; FDD; SSI; Experimental Modal Analysis; Noise and Vibration Test;

    Abstract : The prototypes vibration test carried out for obtaining reliable information concerning machine’s dynamic properties in development process. Analysis results should be able to correlate with FE model to determine if some underlying assumptions (material properties & boundary conditions) were correct. READ MORE

  5. 24. Methodology and vibrational analysis for measurements on a VTOL RAPS

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Dino Krantz; [2017]
    Keywords : Experimental modal analysis; impact hammer test; methodology; structural vibration; RPAS; VTOL; Certification;

    Abstract : In this thesis a methodology for measuring vibrations has been produced andinvestigated for APID 60, a rotorcraft in a Vertical Take-off and landing remotelypiloted aircraft system (VTOL RPAS). A comparative study was carried out forthe purpose of identifying the methodology with respect to design modificationscommon to the APID 60. READ MORE

  6. 25. Brake noise : A study in multi-tonal brake squeal

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Viktor Wiese; [2017]
    Keywords : ;

    Abstract : Brake squeal is a major problem for the vehicle industry due to recla-mations and quality perception of vehicles, as well as the unpredictability of its occurrence. This report investigates the physical reasons behind a multi-tonal brake squeal generated in a motorcycle disc brake. READ MORE
