AB - This paper presents the complex analytical transducer model of a Permanent Magnet Synchronous Motor (PMSM) for vibroacoustic applications, meaning when the motor actually does not rotate but only the rotor oscillates with low amplitude around an equilibrium position relative to the stator. Using only two assumptions - sinusoidal air-gap flux density and evenly distributed winding - the single phase transducer model is introduced, which is then extended to cover motors with any number of phases. The article proposes adequate transducer symbols and transmission equations as well. In order to enhance the practical relevance of the proposed approach, it is shown that using complex amplitudes and appropriate phase shift vectors in the transducer equations, a complex parameter transducer model can be obtained for sinusoidal signals. © Published under licence by IOP Publishing Ltd.

Comparing the vibration level in the superstructure in an isolated setup with that obtained in a non-isolated setup, the performance of the BBI system can be directly calculated. However, in practice, a non-isolated building does not exist. Recently, in the frame of the EUROSTAR BIOVIB project (Building Insulation against Outdoor Vibrations), based on Power Flow Insertion Gain (PFIG), a simplified performance indicator has been introduced. The new indicator is defined in terms of the measured transmissibility in the isolated building and the mobilities of the superstructure and substructure. To validate the proposed performance indicator, a full-scale test bench has been developed. The test bench has three main parts: (1) a substructure (foundation), (2) an isolation bearing and (3) a superstructure. The superstructure consists of a concrete column and four steel blocks being hung from the column by four springs representing the effect of floor resonance frequencies. The substructure (foundation) is a thick steel plate supported by four thin pads. The performance of a selected BBI system has been determined by the proposed indicator and then compared with that measured by the direct insertion loss in the test bench. The proposed indicator shows a reasonable agreement with the direct insertion gain up 100 Hz in the frequency range of ground borne vibration due to railway induced vibrations. © 2021, Springer Nature Switzerland AG.

The analogy between typical linear transducers (like a loudspeaker or a shaker) and rotational transducers (e.g.: PMSMs) is also presented and it is shown that the classical transducer models can be used for PMSMs with arbitrary number of phases too if complex amplitudes are introduced for the phase currents and phase voltages and appropriate complex transformation vectors are applied. © "Advances in Acoustics, Noise and Vibration - 2021" Proceedings of the 27th International Congress on Sound and Vibration, ICSV 2021.

Methods to do so exist from simple analytical formulae to full-size detailed numerical analysis of vibrations and re-radiated noise. Nevertheless, designers need an effective, practicable method to ensure that the interior noise of buildings planned above or in the vicinity of metro lines do meet the relevant limit values and to decide whether or not building base isolation is required. The paper summarizes a number of experiments performed in large portal frame buildings consisting of simultaneous vibration and noise measurements. It was established that the accuracy of the well-known Kurzweil formula [3] is highly limited: the difference between measured and predicted sound pressure values is frequency dependent with positive values for low and negative values for higher frequencies, and the standard deviation of the predictions is high. The experimental findings were pursued by numerical calculations for a very simple model, consisting of various typical wall and floor slab materials and dimensions. It was found that the positive difference for low frequencies is mainly caused by weak fluid-structure coupling. The large spread is related to the highly modal behavior of both the involved structures and the acoustic field, resulting in strongly frequency-dependent sound radiation from the surrounding surfaces. As a result, an improved prediction formula is proposed on the basis of the comparison of measured and simulated difference curves.

The first task was to determine the noise reduction efficiency of automated rail lubrication: noise measurements were performed in case of lubricated rails with corrugations, non-lubricated rails with corrugations, grinded rails as well as grinded and lubricated rails. Once the conformity was determined, an additional task was to find the right lubricant. After the noise and braking effect tests of various lubricants, it was a legitimate need to determine the optimum lubricant application because the setting of the devices is based only on the experience of the Operator. Finally, the noise mitigation effect and the friction coefficient affecting the wheel/rail contact with different lubricant application settings were investigated simultaneously. It is important that the lubricant be applied in appropriate amount such that even the safe movement of the trams is guaranteed, but at the same time the noise reduction is satisfactory too. Based on the results, the authors make recommendations for the application of the rail lubrication devices. LA - English DB - MTMT ER - TY - CHAP AU - Kimpián, T.
