VIBRATING TABLE SYSTEM AND CONTROL METHOD THEREFOR

Title:

VIBRATING TABLE SYSTEM AND CONTROL METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/1997/011344

Kind Code:

A1

Abstract:

A vibrating table system comprising a vibrator, a vibrating table and a controller for controlling the vibrator so as to reproduce target acceleration waveform by use of at least an accelerator measurement signal as a feedback signal. The load of a specimen mounted on the vibrating table exerted on the vibrating table is used as the feedback signal so as to correct the control error due to the load. Especially for a specimen of a non-linear system whose dynamic characteristics change with time, a high degree of acceleration reproducibility is achieved.
