  1. 41. Application of transmissibility measurement in estimation of modal parameters for a structure

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : AmirHossein Aghdasi; [2013]
    Keywords : Operational Modal Analysis; Transmissibility measurement; mode shape; MATLAB.;

    Abstract : Identification of modal parameters from output-only data is studied in this work. The proposed methodology uses transmissibility functions obtained under different loading conditions to identify resonances and mode shapes. The technique is demonstrated with numerical simulations on a 2-DOF system and a cantilever beam. READ MORE

  3. 42. Electromagnetic Noise from Permanent Magnet Motors

    University essay from KTH/Farkost och flyg

    Author : Sajan Varghese; [2013]
    Keywords : ;

    Abstract : With today’s increase in rail traffic the impact of noise on the people near railway lines is increasing. To control this problem European Union regulations, including TSI (Technical Specifications for Interoperability) Noise, has come into force by implementing many strict norms on new railway vehicles put on the market.

  4. 43. Welded Frame Finite Element Modelling and Experimental Modal Analysis

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Muralikrishna Koduri; Woodrow Wilson Wilson Devadoss; [2013]
    Keywords : Finite element model; Modal analysis; Experimental Investigation; Modal Updating;

    Abstract : In this modern developing world finite element model is one of the main tools and they are becoming more and more advanced day by day in all mechanical fields. Before manufacturing a product the demands for finite element model is more between the manufacturers. READ MORE

  5. 44. Model calibration of a wooden building block

    University essay from Institutionen för bygg- och energiteknik (BE)

    Author : Ali Abdul Jabbar Karim; Johan Lessner; Mehrdad Moridnejad; [2013]
    Keywords : Wood; Dynamical behaviour; Finite element model; light weight assembly; Experimental modal analysis; Wooden;

    Abstract : Constructing multi floor buildings by light weight material have increased recently. There are many advantages of using light weight material, such as wood, for the environment. However, one of the deficiencies of lightweight material is the acoustic performance. READ MORE

  6. 45. Characterization of Dynamic Elastic Modulus and Damping Property of CNx Coating Material by Experimental Modal Analysis and Finite Element Approach

    University essay from KTH/Industriell produktion

    Author : Md. Masud Ur-Rashid; [2013]
    Keywords : ;

    Abstract : Free-layer hard or soft coating material can be used for enhancing the inherent damping capacity (energy dissipation ability) of a structure under cyclic bending deformation. This may help to attenuate the vibration amplitude at the resonance frequency. READ MORE
