Simultaneous Analysis of Noise and Vibration of Machines in Vibroacoustic Diagnostics
Publié 2016-12-01Accéder au texte intégralThe article is a continuation of the authors' elaboration (Dąbrowski, Dziurdź, 2016). The aim of this continuation is to prove that a proposed way of modelling and using the coherent analysis to filter nonlinear disturbances is a useful technique in vibroacoustic diagnostics. The thesis was pro...

Simultaneous Analysis of Vibrations and Noise in the Task of Minimizing Vibroacoustic Activity of Machines
Publié 2016-04-01Accéder au texte intégralSimultaneous propagation of vibrations and noise has an important role in the task of minimizing vibroacoustic hazards on the station of operator of the construction machinery. In many cases vibrations transferred by the construction are processed to noise in different points of the machine. As a re...

Selection of Sound Insulating Elements in Hydraulic Excavators Based Onidentification of Vibroacoustic Energy Propagation Paths
Publié 2013-12-01Accéder au texte intégralIn spite of the fact that standardizing operations and increased awareness of hazards led to a significant improvement of vibroacoustic climate of operator’s stands of new machines, their long-term operation – often under difficult conditions – leads to a fast degradation of acoustic qualities of...

Separations of Strategic Metals from Spent Electronic Waste Using “Green Methods”
Publié 2025-06-01Accéder au texte intégralNext-generation recycling technologies must be urgently innovated to tackle huge volumes of spent batteries, photovoltaic panels or printed circuit boards (WPCBs). Current e-waste recycling industrial technology is dominated by traditional recycling technologies. Herein, ionic liquids (ILs), deep eu...

Studies on propagation of vibroacoustic energy and its influence on structure vibration in a large-size object
Publié 2014-05-01Accéder au texte intégralLarge-size spaces of general use are usually characterized by atypical acoustic features. The Great Lecture Hall of Warsaw Technical University can be an example, as its maximum crosswise dimension is comparable with its height. When powerful amplification equipment is used for special events, the q...

Utilisation of the Coherence Analysis in Acoustic Diagnostics of Internal Combustion Engines
Publié 2017-07-01Accéder au texte intégralThe leading thought of the present text is that the internal combustion engine noise – regardless of all possible inconveniences – is a good information carrier that allows for the explicit diagnostics of such subtle defect as the valve face decrement which is so small that it is in practice ‘unnoti...
