Abstract

A spectral response function is derived based on a vibration equation on flexible plants. Measured spectrum on turbulence in flow over flexible plants is used to calculate the vibration spectrum of plants. It is found that the vibration of flexible plants has two peaks corresponding to resonant vibration of each plant and honami. The predicted profile of spectrum for plant vibration agrees very well with the result of wind tunnel tests. It is concluded that the honami is induced by organized vortices generated by a shear instability of flow.
