Vibration intensity technique is used to measure vibration power transmission in thin single layerudtechnical orthotropic plates for flexural waves. Measurement of flexural wave power is carried out in far-udfield conditions. All measurements are undertaken in the frequency domain using the cross-spectra ofudacceleration signals, facilitating the use of FFT analyzer. The two-transducer technique applicable to theseudplates is used for these measurements. Technical orthotropic (rectangular corrugation) plates of steel areudused for the measurements. One isotropic plate of steel is also considered for comparison. Method of elasticudequivalence technique is used. Both input power and vibration power transmission through the plates areudestimated. Far-field power is normalized with the input power for flexural wave. Influence of flexuraludrigidity on vibration energy transfer is also investigated.
