  1. 21. Evaluation of a Contactless Excitation and Response System (CERS) for process planning applications : An experimental study

    University essay from KTH/Industriell produktion

    Author : Laura Montalban; [2016]
    Keywords : mechanical vibrations; natural frequencies; damping ratio; chatter; structural dynamic tests; stability lobe diagrams.; mekaniska vibrationer; egenfrekvens; dämpning; chatter; strukturdynamiska tester; stabilitetsdiagram.;

    Abstract : Chatter vibration is a common problem for the manufacturing industry that limits the productivity, accuracy and surface quality of machined parts. This study is focused on the out of process methods, such as Stability Lobe Diagrams (SLD), that ensure the selection of the optimal cutting parameters in which the machining process is stable.

  3. 22. Pilot Testing of a Hydraulic Bridge Exciter

    University essay from KTH/Bro- och stålbyggnad

    Author : Richard Borg; Olivier Dymén; [2015]
    Keywords : Hydraulic bridge exciter; controlled excitation; modal testing; experimental modal analysis; railway bridges; measurements; load shaker; FEM; FE-modelling; script; Hydraulisk broexciterare; kontrollerad excitering; modala tester; experimentell modal analys; järnvägsbroar; mätningar; lastexciterare; FEM; FE-modellering; script;

    Abstract : In the design of a railway bridge that is meant for train speeds larger than 200 km/h, the Swedish Traffic Administration requires a dynamic analysis in addition to the conventional static design. The models used for static design may not always be suitable for dynamic analysis, which could lead to inaccurate estimations of the dynamic response. READ MORE

  4. 23. Comparison of Analysis and Measurement Results for a ST1530 Loader Regarding Dynamic Behavior of Engine Cradle

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Christoper Gustafsson; Mohamed Hemdan; [2015]
    Keywords : Ansys; FEM; Response analyse;

    Abstract : This thesis is a measurement evaluation type of project in which to perform a harmonic response analysis were the results will be compared to measurement data to verify if the ANSYS model is realistic in terms of dynamics. This includes proposing the different parameters that will affect the results of the comparison as well as how to improve further models. READ MORE

  5. 24. Modeling of Fuel Dynamics in a Small Two-Stroke Engine Crankcase

    University essay from Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska fakulteten

    Author : Johan Andersson; Oscar Wyckman; [2015]
    Keywords : Modeling; Event based modeling; Two-stroke engines; Crankcase; Fuel dynamics; Wall wetting; Gas mixing;

    Abstract : For any crankcase scavenged two-stroke engine, the fuel dynamics is not easily predicted. This is due to the fact that the fuel has to pass the crankcase volume before it enters the combustion chamber. READ MORE

  6. 25. Modeling of a vehicular LNG tank with regard to real time implementation

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Christian Wessel; [2015]
    Keywords : ;

    Abstract : The usage of natural gas (NG) as an alternative vehicle fuel is becoming more and more common, due to a factor of approximately 600 between the liquid and vapour phase density, the storage of liquefied natural gas (LNG) in cryogenic containers is desirable to enable for NG propelled long haulage vehicles. Due to the novelty of the LNG vehicular market, little research in the field “modeling of LNG vehicular tanks” exists. READ MORE
