[Sample 2]
S-43 manufactured by Nestor Martin was used as the stove, and all the legs of the stove were fixed to the floor.

[Test method]
For the samples 1 and 2 configured as described above, using the strong earthquake response test equipment installed at the Disaster Prevention Research Institute at Kyoto University, the following three types of earthquakes were simulated and the samples were subjected to seismic tests. Went.
(1) Hyogoken-Nanbu Earthquake "Kobe Wave"
(2) Tohoku Pacific Ocean Earthquake “Haganami”
(3) Kumamoto earthquake "Mashiro wave"

Specifically, acceleration and displacement simulating the above-described earthquake were reproduced in a strong earthquake response test apparatus, and the strain amount of the leg portion in the X direction and Y direction of the sample placed on the shaking table was measured.
For this measurement, sensors were attached to the front (Y direction) and side (X direction) of the sample stove, and at two locations, the boundary between the stove body and the leg. This sensor is a strain sensor, and is composed of a long metal piece to which both ends are attached so as to straddle the boundary between the stove body and the leg part, and a sensor body fixed to the metal piece. The sensor is connected to an amplifier and an A / D converter. With this configuration, when a force is applied to the leg due to the shaking of the earthquake, the metal plate bends and returns, so the sensor body detects this change as a resistance value. The detected signal is amplified using an amplifier, digitally converted using an A / D converter or the like, and then output as a distortion amount.

Next, the test results of the Tohoku Pacific Ocean Earthquake “Haganami” are shown in FIGS.
As shown in FIG. 10, sample 2 in which only the legs are fixed is distorted in the legs in proportion to the displacement and acceleration of the shaking table shown in FIG. 11 in both the X and Y directions as in (1). On the other hand, it can be seen that the sample 1 in which the seismic unit of the present invention is installed has almost no distortion in the legs.

(3) Kumamoto earthquake "Mashiro wave"
Finally, the test results of the Kumamoto earthquake “Mashiro wave” are shown in FIGS.
As shown in FIG. 12, sample 2 in which only the legs are fixed is applied to the legs in proportion to the displacement and acceleration of the vibration table shown in FIG. It can be seen that the sample 1 with the seismic unit of the present invention is hardly distorted in the legs, while the distortion is generated.

  From the test results of (1), (2), and (3) above, it is clear that when the seismic unit of the present invention is used, the legs are not distorted and the stress applied to the legs is greatly reduced. It became. Therefore, if the seismic unit according to the present invention is used, it is possible to prevent the leg from being broken due to the shaking of the earthquake, and to prevent damage to the building caused by the fall of the stove during the earthquake disaster.
