- 1512aba0fde411eebc4dd58f108bcb6b description "The topic of modal analysis is mature and has been extensively addressed over the past sev-eral decades. A survey, however, suggests a lack of documentation simply explaining modal analysis, from a practical point-of-view, for example for a simple, multi-degree-of-freedom (MDoF) system, using a range of common, different analytical, numerical and experimental methods. This tutorial paper therefore aims to discuss the topic of modal analysis in the con-text of a simple eight-storey tower structure utilising a range of such commonly deployed, industrially relevant approaches. The datasets, as well as the associated coding and simula-tion files, are made readily available to help non-specialist readers, for example junior re-searchers or early career stage industrial practitioners, develop their understanding and to replicate specific or all elements of the study should they wish to do so. A vertically orientated, mild steel rectangular hollow cross-section cantilever beam was en-gineered in a laboratory to have eight rigid lumped masses mounted at evenly distributed in-tervals along its length. Structural excitation was performed in two different measurement regimes using an impact hammer (“roving hammer”) and an electrodynamic shaker (“roving response”). An accelerometer, a laser Doppler vibrometer, and a laser triangulation sensor were used to measure the acceleration, velocity, and displacement response of the structure, respectively. The complete procedure for sensitivity determination of the response transducers is presented and the extraction of modal features using the different transducers is discussed in detail. A corresponding simplified finite element model of the system is presented, considering the beam as a continuous system with eight finite mass elements. An analytical model using Eu-ler-Bernoulli beam theory was also prepared with correction factors compensating for the effect of the added masses. In addition, a lumped parameter model of the structure was cre-ated considering the masses as point masses and the beam as massless springs. Finally, com-putational simulation of the problem was conducted in SolidWorks, with a convergence study utilised to find the most appropriate mesh densities. The experimental datasets, the MATLAB scripts for the numerical and analytical methods, as well as the SolidWorks simu-lations are made freely available in a data repository . " assertion.
