Abstract. The article is devoted to improving automation systems for vibroacoustic monitoring of the stability and safety of structures. The aim of the study is to develop and experimentally validate digital models of wave processes for data processing tasks in vibroacoustic monitoring used in the practical assessment of the state and safety of engineering structures. Methods: analysis of experimental data; software-based construction of digital models; laboratory experiments; and modeling of transverse wave propagation. The analysis demonstrated the relevance of conducting laboratory studies of wave processes to verify theoretical models and to identify characteristic features and hidden patterns in the dynamics of wave propagation in various media. A functional scheme of a laboratory plant for generating vibroacoustic oscillations was developed and tested at the authorized training center of the French electromechanical corporation Schneider Electric at Dnipro University of Technology. Algorithms and software were created for modeling the propagation of excitation and reflected transverse waves. Monochromatic harmonic oscillations were generated with subsequent frequency increase, and pulse excitation and switching waves were simulated. Experimental results showed that when interacting with an absorbing boundary, the amplitude of the transverse wave decreases while the waveform and main characteristics of the wave process remain stable during further propagation. A significant pattern for vibroacoustics was observed: wave propagation has a deterministic nature with superimposed stochastic components caused by complex reflection conditions. A new approach to vibroacoustic data analysis was developed, involving the construction of digital vibration excitation models to create digital twins of real wave processes through frame-by-frame temporal visualization and color mapping of time intervals. This enables comprehensive analysis of oscillations and wave propagation processes in complex structures. The results obtained can be used for practical interpretation of vibroacoustic signals and for monitoring the safety of engineering structures.
Keywords: safety of structure operation, automation of vibroacoustic control, wave process models, data processing, digital filters.
