trillingsanalyses

Trillingsanalyses is a field of study focused on analyzing vibrations in physical systems, such as machinery, structures, and acoustic environments. The term derives from Dutch and Scandinavian roots where trillingen or trillande means vibration, and analyses denotes systematic examination. The discipline seeks to quantify amplitude, frequency, phase, and damping, and to interpret how these properties affect performance and integrity.

Methodologically, trillingsanalyses combines experimental measurement with computational analysis. Data are collected with accelerometers, laser vibrometers, and other sensors, then processed by time-domain and frequency-domain techniques. Common approaches include Fourier analysis, short-time Fourier transform, and wavelet analysis, plus system identification to build models of dynamic behavior.

Applications include preventive maintenance, structural health monitoring, automotive and aerospace engineering, electronics, and musical acoustics. It supports fault diagnosis, vibration suppression design, and performance evaluation under operational loads, and contributes to material characterization, resonance studies, and active or passive vibration control strategies.

History and scope: Advances in sensors and digital signal processing have shaped the field, drawing on mechanical engineering, physics, and data science. Terminology varies by region, but trillingsanalyses generally aligns with vibration analysis and structural dynamics, and it continues to evolve with data-driven methods.
