  1. 31. 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

  3. 32. Dynamic characterization of the tool holder material : An Experimental Thesis

    University essay from KTH/Industriell produktion

    Author : Mayank Kumar; [2015]
    Keywords : ;

    Abstract : The major factors putting limitation to high productivity and good product surface quality is machining vibration. A lot of scientific research has been concentrated controlling the vibration while machining. READ MORE

  5. 34. Modal Analysis on a MIMO System : For an asphalt roller CC1200

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : You You; Daxin Chen; [2015]
    Keywords : Experimental modal testing; MIMO system; modal analysis; Matlab; numerical model; Reflex.;

    Abstract : Impact hammer is the current modal testing way in Dynapac testing department. Due to highly damped characteristic of big construction machines, there are a few weaknesses for modal testing when using hammer, such as short response time, limited frequency resolution, poor quality of frequency response functions.

  6. 35. Vibrational measurement techniques applied on FE-model updating

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Yaolun Wang; [2015]
    Keywords : vibrational test; modal analysis; FE-model; Abaqus;

    Abstract : In this thesis, the dynamics of two plates overlapping and connected by three bolts are studied. The data collected in the test are used in modal analysis. The vibrational test and the modal analysis were made using an LMS system. Hammer excitation is used for the tests. READ MORE
