ABSTRACT
In this study, the application of the Time Difference of Arrival (TDoA) method was investigated to locate impulse excitations in steel components. The research employs a hierarchical modeling approach, beginning with simple rectangular steel plates, advancing to bent L-shaped plates, and ultimately targeting realistic car chassis elements. This article highlights how structural features influence wave propagation and localization accuracy. The results demonstrate that TDoA can reliably identify impulse locations in simple structures, highlighting its potential as a robust tool for diagnostics in automotive engineering. The study provides a foundational framework for extending TDoA-based diagnostics from laboratory-scale experiments to full-scale vehicle applications.
