STUDY ON ERROR REDUCTION OF CONTACT RESONANCES USING VIBRATION CONTROL RUBBER FOR VERTICAL VIBRATION OF TATAMI

We have conducted various studies on methods to prevent contact resonances. It was suggested that the proposed method of the previous studies could be used to estimate carpets and building material tatami. On the other hand, there was a problem with the straw tatami. Therefore, in this report, we conducted an experimental study on an estimation method that is an extension of the proposed method. As a result, it was shown that by considering the modified estimation method, the error of the contact resonances can be reduced and estimated even with the straw tatami.
