Abstract
In this paper, impedance of the chiller foundation for ships is studied by using FEM and prediction is compared to measurements. Small and medium weight hammer are used to cover high and low frequency ranges in impedance measurements. Comparison shows that measurement and prediction is in good agreement in which coherence is higher than 0.98 for the frequency ranges of 40-50 Hz to 1600 -2000 Hz.
