Abstract

PURPOSE:To improve regeration accuracy to a remarkable extent by a method wherein a vibration stand is vibrated by an oscillating signal such as the one with a random wave containing the whole frequency band constituting a target oscillating wave or a target oscillation number, so that vibration and correction are alternatively repeated. CONSTITUTION:An oscillating signal C1 is given in a digitallized form by dividing on a preset minute time basis a random wave containing the whole range of wavelengths constituting a particular seismic wave, an oscillating wave or the like as a regeneration target, or a target oscillating wave, the signal being stored in a first memory beforehand. An analog signal obtained by a D/A converter is amplified, before being sent to an oil hydrauic system to operate an actuator which vibrates a vibration stand carrying a specimen. By converting an actual oscillating signal into a digital form in order to obtain a transfer function of a vibration system as a whole containing the specimen in the form of a digital signal, and the oscillating signal is corrected using this transfer function. By repeating vibration and correction in this manner, regeneration accuracy can be improved to a remarkable extent.
