1. 1. FRF Based Experimental – Analytical Dynamic Substructuring Using Transmission Simulator

   Master-uppsats, KTH/MWL Marcus Wallenberg Laboratoriet

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

   Sammanfattning : 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. LÄS MER

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

   Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

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

   Sammanfattning : 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). LÄS MER

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

   Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

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

   Sammanfattning : 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. LÄS MER

5. 4. Evaluation of time varying stresses in a Howden fan

   Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

   Författare :Tim van Mierlo; Rafal Żywalewski; [2015]
   Nyckelord :Finite element analyses; Dynamic substructuring; Axial flow fan; Blade; Rotor dynamics; Centrifugal force;

   Sammanfattning : In this work, the time varying stresses in a Howden axial flow fan are obtained by finite element analyses. Dynamic substructuring is used to obtain accurate values of the stresses in the threads of the blade shaft, the component which connects the blade with the hub. LÄS MER

7. 5. Dynamic Substructuring of an A600 Wind Turbine

   Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

   Författare :Ahmed Al Kaysee; Marek Wronski; [2014]
   Nyckelord :Substructural techniques; wind turbine; blade; decoupled; FRF; dynamic substructuring.;

   Sammanfattning : A limited and extendable master thesis is representing the first step in the experimental substructuring of an A600 wind turbine. Additional masses have been designed, manufactured and added to the sub components for the laboratory experimental tests. Further preparations for dynamic experimental tests have been described and implemented. LÄS MER
