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

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 paper, we conducted an experimental study on an estimation method that is an extension of the proposed method for vertical and horizontal vibration. As a result, it was shown that by considering the proposed modified estimation methods, the error of the contact resonances can be reduced and estimated even with the straw tatami.
