  1. 1. Approximating Damping Coefficient of Bolted Joints using the Finite Element Method

    University essay from KTH/Hållfasthetslära

    Author : Abhiroop Chatterjee; [2023]
    Keywords : ;

    Abstract : Bolted joints are important due to their energy dissipation property in structures,but the damping mechanism is also highly nonlinear and localized. The goal ofthis thesis is to develop an accurate method for modeling bolted joint dampingin large structures using finite element (FE) software. READ MORE

  3. 2. Component-Based Transfer Path Analysis and Hybrid Substructuring at high frequencies : A treatise on error modelling in Transfer Path Analysis

    University essay from KTH/Maskinkonstruktion (Avd.)

    Author : Harikrishnan Venugopal; [2020]
    Keywords : Dynamic Substructuring; Error modelling; Transfer Path Analysis; Uncertainty Propagation; Dynamisk substrukturering; Feluppskattning; Överföringsanalys; Osäkerhetspropagering;

    Abstract : The field of modal testing and analysis is currently facing a surge of interest in error modelling. Several errors which occur during testing campaigns are modelled analytically or numerically and propagated to various system coupling and interface reduction routines effectively. READ MORE

  4. 3. FRF Based Experimental – Analytical Dynamic Substructuring Using Transmission Simulator

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Krishna Chaitanya Konjerla; [2016]
    Keywords : Dynamic substructuring; Transmission Simulator; Modal Analysis; Experimental-Analytical; FRF Based Substructuring; MCFS; Hybrid Coupling;

    Abstract : In dynamic substructuring, a complex structure is divided into multiple substructures that can be analysed individually and these individual component responses are coupled together to obtain the global response of the whole structure. Dynamic substructuring can be performed on substructure models that are identified either experimentally or analytically. READ MORE

  5. 4. Experimental Dynamic Substructuring of an Ampair 600 Wind Turbine Hub together with Two Blades : A Study of the Transmission Simulator Method

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Tim Johansson; Magdalena Cwenarkiewicz; [2016]
    Keywords : Experimental dynamics; FBS; Frequency Based Substructuring; FRF; Frequency Response Function; Coupling; Decoupling; Transmission simulator method; Ampair 600; A600;

    Abstract : In this work, the feasibility to perform substructuring technique with experimental data is demonstrated. This investigation examines two structures with different additional mass‑loads, i.e. transmission simulators (TSs). READ MORE

  6. 5. Experimental substructuring of an A600 wind turbine blade  : A study of the influence of interface loading

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Judas Santos; Nidaa Al-Mahdi; [2016]
    Keywords : Experimental dynamic substructuring; Transmission simulator technique; FRF-based substructuring; interface loading; standard collocated method; coupling; decoupling; uncoupling; Ampair 600; wind turbine blade;

    Abstract : Dynamic Substructuring is a powerful tool for simplification of the analysis of complex structures and it has been well established along the years in analytical calculations by means of the Craig-Bampton technique. Recently, a new branch of substructuring, the Experimental Dynamic Substrucuring, appeared as a promising field of research for the engineering community. READ MORE
