A simple hybrid approach on predicting the vibration transmission of rib-stiffened plates

Accurate predictions of vibration transmission of rib-stiffened plates can be quite problematic in that both long- and short-wavelength deformations are commonly generated within the same system model. In this case, it is widely acknowledged that hybrid methods which can combine both the deterministic and statistical modelling techniques are more appropriate than single deterministic or statistical methods. In this paper, a simple hybrid technique, i.e., the so-called “mode-based approach”, is applied to predict the vibration transmission of a rib-stiffened plate model. The results are then compared with those of the well-established hybrid FE/SEA method and the exact modal analysis. It is found that the mode-based approach has a better performance than the hybrid FE/SEA method regarding both accuracy and efficiency, although the former is far less generic than the latter at the current stage.
