Dynamic response of certain structures to random excitation of turbulent flow type

Prediction of the structure response to the random excitation and proper interpretation of the observed data can be aided by a beforehand knowledge of the structure behaviour subjected to the certain excitation type prevailable under known circumstances.This knowledge can be also useful in determining unknown parameters of the excitation on the basis of the response measurements.The publication studies the response of the pipes and cylindrical shells to the turbulent flow excitation employing the mode superposition method.The research was carried out in the Vibration and Seismic Laboratory of CEN, Saclay, France, within the framework of the Franco Finnish scientific cooperation.
