Therefore, it is of major interest to analyse the dynamic behaviour of these elements. In the present work, the characterisation of the damping of an elevator rope was carried out. Three type of damping estimation methods were analysed. First, the Half Power Bandwidth (HPB) method was used. In addition, due to the low signal quality obtained in some results, the logarithmic decrement method was employed. Finally, experimental Modal Analysis (EMA) algorithms were carried out. According to the results, similar damping values were obtained with the three methods. Thus, it is confirmed that the HPB method is the most interesting procedure. On the one hand, it is not necessary a previous signal conditioning that requires the definition of the filtering conditions by the analyst. On the other hand, instead of measuring the acceleration response of several points, only one acceleration response signal is enough 978-90-828931-5-1 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=168400 https://hdl.handle.net/20.500.11984/6381 Damping characterisation of an elevator rope
