    • Analysis of the dynamic characterisation and behaviour of an elevator rope 

      Mendizabal, Mikel; Iriondo, Jaione; McCloskey, Alex; Otaño Aramendi, Nerea; Galfarsoro, Unai; Hernández García, Xabier (ISMA - International Conference on Noise and Vibration Engineering, 2020)
      The ropes of an elevator transmit the vibrations from the motor to the elevator car, and consequently have a great influence on comfort. Therefore, it is of major interest to analyse the dynamic behaviour of these elements, ...

    • Analysis of the noise attenuation in ducts by means of rigid perforated panels 

      McCloskey, Alex; Guiral García, Ainara; Iriondo, Jaione; Galfarsoro, Unai (ISMA - International Conference on Noise and Vibration Engineering, 2020)
      The noise of Heating, Ventilating and Air Conditioning (HVAC) systems is an important aspect to take into account when the comfort of the users is compromised. For instance, passengers in trains perceive this noise, which ...

    • Comfort improvement of an elevator car by viscoelastic sandwich panels 

      Mendizabal, M.; Iriondo, Jaione; Hernández García, Xabier; McCloskey, Alex; Irazu, Leire (ISMA - International Conference on Noise and Vibration Engineering, 2020)
      Viscoelastic sandwich structures have become one of the most important techniques to reduce structural vibrations. These structures have a great damping capacity due to their viscoelastic core, and their metallic skins ...

    • Damping characterisation of an elevator rope 

      Iriondo, Jaione; McCloskey, Alex; Irazu, Leire; Galfarsoro, Unai (ISMA, 2022)
      The ropes of an elevator transmit the vibrations from the motor to the elevator car, and consequently have a great influence on comfort. Therefore, it is of major interest to analyse the dynamic behaviour of these elements. ...

    • Fast and Accurate Vibration Response Calculation Procedure for Permanent Magnet Synchronous Machines 

      Mendizabal, Mikel; McCloskey, Alex; Zárate Barriga, Sergio; Poza, Javier (IEEE, 2022)
      The vibration of the stator frame due to electromagnetic forces is one of the main noise and vibration sources of electric machines. In some applications, due to the wide variety of working conditions, design optimizations ...

    • Influence of Manufacturing Tolerances and Eccentricities on the Electromotive Force in Permanent Magnet Synchronous Motors 

      Galfarsoro, Unai; McCloskey, Alex; Zárate Barriga, Sergio; Almandoz, Gaizka (IEEE, 2022)
      Eccentricity is a common error in electric motors, so its diagnosis is an important issue. Therefore, the effect of static and dynamic eccentricities on the harmonics of the frequency spectra of the voltage of a phase is ...

    • Influence of manufacturing tolerances and eccentricities on the unbalanced magnetic pull in permanent magnet synchronous motors 

      Galfarsoro, Unai; McCloskey, Alex; Zárate Barriga, Sergio; Almandoz, Gaizka (IEEE, 2020)
      Eccentricity is an inevitable fault in electric motors and hence its diagnosis is an important topic. Thus, the influence of static and dynamic eccentricities on the harmonics of the frequency spectra of the unbalanced ...

    • Makina Elektrikoen Portaera Bibroakustikoaren Neurketa eta Simulazioa 

      McCloskey, Alex; Arrasate, Xabier (UEU, 2015)
      Noise and vibration of electrical machines is a major concern. Changes in the machine design to improve its ef f iciency can lead to unacceptable vibrations. Tools to predict its vibratory and acoustic performance at the ...

    • Noise attenuation prediction and analysis in rectangular lined ducts 

      McCloskey, Alex; Iriondo, Jaione; Aizpuru Nazabal, Aitziber (ISMA, 2022)
      The noise of Heating, Ventilating and Air Conditioning (HVAC) systems is an important aspect when the comfort of the users is compromised. Thus, solutions to attenuate that noise need to be proposed. Linings in ducts are ...
