The material of the cushioning material 31 is not particularly limited, but polyurethane elastomer, anti-vibration rubber, etc., which have relatively high anti-vibration performance and can change the dynamic spring constant depending on the area to be loaded, are particularly preferable. An ether-based foamed polyurethane elastomer that can lower the frequency and obtain an appropriate cushioning effect over a wide load range by changing the component composition is preferable.
The size and thickness of the cushioning material 31 are not particularly limited, but generally, the size is preferably about 25 cm ² (for example, 5 cm × 5 cm) to 400 cm ² (for example, 20 cm × 20 cm), and the thickness is preferably about 10 mm to 50 mm.

The vibration-proof floor device of the present invention has a dynamic spring constant and a loss coefficient (dynamic loss) of the cushioning material 31 so that the cushioning material can be replaced according to the load (load) and the easiness of shaking of the article g to be transported. It is preferable to have a plurality of sets of pieces 3 having different rates). In the anti-vibration floor device of the embodiment of FIGS. 1 to 8, since the floor member 1 is supported on the floor portion f via the 18 pieces 3, the pieces 3 are a set of 18 pieces. 18 pieces are one set of pieces 3, and each set is provided with a plurality of sets of pieces 3 having different dynamic spring constants or / and loss coefficients of the cushioning material 31, and the load by the article g to be transported or / and the article g. The set of pieces 3 to be used can be selected and exchanged (changed) according to the easiness of shaking. Here, in the present invention, the dynamic spring constant is measured according to JIS K6385, and the loss coefficient is measured according to DIN 53513.
Since each piece 3 is removable from the floor member 1, the number of pieces 3 attached to the floor member 1 is reduced as necessary (that is, less than 18 pieces) depending on the article g to be transported. You may do it.

The plurality of pieces 3 in one set may include the cushioning material 31 having a different dynamic spring constant and / or loss coefficient. In that case, the “dynamic spring constant of the cushioning material 31” for each set may be provided. Is the total value of the dynamic spring constants of the cushioning material 31 of all the pieces 3 in one set, and the "loss coefficient of the cushioning material 31" for each set is the total value of all the pieces 3 in one set. The combined loss coefficient is based on the loss coefficient of the cushioning material 31 of. Here, for example, when the dynamic spring constants of the cushioning material 31 of each piece 3 are the same, the combined loss coefficient η of the cushioning material 31 is the total number of the pieces 3 of X pieces, of which the cushioning material having the loss coefficient ηa is the cushioning material. If the piece 3 using the loss coefficient ηb is x ₁ , the piece 3 using the cushioning material with the loss coefficient ηb is x ₂ , the piece 3 using the cushioning material with the loss coefficient ηc is x ₃ , and so on. It can be obtained by η = (ηa × x ₁ + ηb × x ₂ + ηc × x ₃ ...) / X.

一般に、防振効果の面では固有振動数は低い方が好ましいが、低すぎると物品ｇの荷重を支えられなくなる。このような観点から、固有振動数は７～３０Ｈｚ程度が好ましい。したがって、緩衝材３１としては、載置する物品ｇによる荷重に応じて、固有振動数が７～３０Ｈｚとなるような動的バネ定数のものを選択することが好ましい。すなわち、輸送する物品ｇの荷重に応じて、固有振動数が７～３０Ｈｚとなるような動的バネ定数の緩衝材３１を備えた駒３のセットを選択して、床部材１に取り付けることが好ましい。 The natural frequency of the vibration isolation system (vibration system) is determined by the dynamic spring constant of the cushioning material 31 and the load of the article g to be placed. That is, the relationship between the natural frequency f _n , the mass m of the article g, and the dynamic spring constant k is expressed by the following equation.

Generally, it is preferable that the natural frequency is low in terms of the vibration isolating effect, but if it is too low, the load of the article g cannot be supported. From this point of view, the natural frequency is preferably about 7 to 30 Hz. Therefore, it is preferable to select a cushioning material 31 having a dynamic spring constant such that the natural frequency is 7 to 30 Hz according to the load of the article g to be placed. That is, it is possible to select a set of pieces 3 provided with a cushioning material 31 having a dynamic spring constant such that the natural frequency becomes 7 to 30 Hz according to the load of the article g to be transported, and attach it to the floor member 1. preferable.

As an example, FIG. 10 shows the relationship between the applied load range and the natural frequency when five types of cushioning materials 31 (vibration-proof pads) having different dynamic spring constants are used. Here, the cushioning materials 31 (cushioning materials A to E) are made of five types of foamed polyurethane elastomers having different dynamic spring constants due to different compositions or sizes. For example, in the cushioning material A, the applied load range is 1161. It can be seen that the natural frequency is within the range of 7 to 30 Hz in the range of ~ 510 kg and in the applied load range of 631 to 330 kg for the cushioning material B, respectively, and an appropriate anti-vibration effect can be obtained. Working load range when the vibration-proof floor device in which nine pieces 3 are arranged on the lower surface of the floor member 1 includes five sets of pieces 3 each having cushioning materials A to E shown in FIG. 10 (depending on the article g). The load range) and the natural frequency in each working load range are shown in Table 1 together with the dynamic spring constants of the cushioning materials A to E. In this anti-vibration floor device, an appropriate anti-vibration effect can be obtained by properly using a set of pieces 3 (selecting and using from 5 sets) according to the load of the article g in the range of 125 to 1161 kg. You can see that.

When the anti-vibration floor device of the present invention includes a plurality of sets of pieces 3 having different dynamic spring constants of the cushioning material 31, the applicable load range of the anti-vibration floor device and the number of sets of the pieces 3 corresponding thereto are not particularly limited. However, in general, the applicable load range of the anti-vibration floor device is set to at least "applicable minimum load to applicable minimum load x 5" (this applicable load range may be further widened), and the piece 3 corresponding to this. It is desirable that the number of sets of is 4 or more (preferably 5 or more). As a specific example, the applied load range of the vibration-proof floor device is at least 200 to 1000 kg (this applied load range may be further widened), and the number of sets of pieces 3 corresponding to this is 4 or more (preferably 5 or more). ).

Further, the article g has a difference in easiness to shake depending on the height of the center of gravity, and when it is desired to obtain a desired damping effect for the article g which is easy to shake (when it is desired to suppress the shaking quickly), a cushioning material having a high loss coefficient is used. It is preferable to use it. Therefore, a plurality of sets of pieces 3 having different loss coefficients of the cushioning material 31 may be provided in the range of the natural frequency (preferably 7 to 30 Hz) as described above and the dynamic spring constant selected accordingly. .. Here, the loss coefficient of the cushioning material 31 should be selected in the range of about 0.05 to 0.6 because the damping effect is poor if it is too low and the vibration isolation effect (vibration reduction rate) is lowered if it is too high. Is preferable.

Here, when the anti-vibration floor device of the present invention includes a plurality of sets of pieces 3 having different loss coefficients of the cushioning material 31, the plurality of sets of the cushioning material 31 having the same dynamic spring constant but different only in the loss coefficient. Although it is possible to include only the pieces 3, usually, a plurality of sets of pieces 3 having different dynamic spring constants of the cushioning material 31 are provided, and dynamic with respect to at least one set of the cushioning materials. A set of pieces 3 having cushioning materials 31 having the same spring constant but different loss coefficients is further provided. Here, the equivalent of the dynamic spring constant means that the value of the dynamic spring constant is within ± 10% (preferably ± 5%). Table 2 shows an example of a vibration-proof floor device equipped with such a set of pieces 3. That is, the anti-vibration floor device shown in Table 2 has a dynamic spring constant equivalent to that of the cushioning materials A to C, in addition to the five sets of pieces 3 each provided with the cushioning materials A to E shown in Table 1. , It is provided with three sets of pieces 3 having cushioning materials A'to C'with a high loss coefficient. The three sets of pieces 3 provided with the cushioning materials A'to C'are selectively used, for example, when an article g having a high center of gravity and easily swaying is placed. The dynamic spring constants of the cushioning materials A'to C'can be made equivalent to those of the cushioning materials A to C by adjusting the sizes (for example, lengths) of the cushioning materials A'to C'.

Of these, FIG. 11A is an example using cushioning materials 31 (cushioning materials A and A'in Table 2) having different loss coefficients in one set, and nine pieces 3 have a loss coefficient of 0.10. It consists of 3: 5 pieces with the cushioning material A and 3: 4 pieces with the cushioning material A'with a loss coefficient of 0.30. On the other hand, FIG. 11A shows an example in which a cushioning material 31 (cushioning material A in Table 2) having the same loss coefficient in one set is used, and all nine pieces 3 are cushioning materials having a loss coefficient of 0.10. It has an A.

Table 3 shows the loss coefficient of the cushioning material 31 in each set of FIGS. 11 (a) and 11 (a) (combined loss coefficient in the case of FIG. 11 (a)), the dynamic spring constant, and the natural frequency at a working load of 800 kg. Is shown. The loss coefficient η (composite loss coefficient) in the case of FIG. 11A is because five cushioning materials A having a loss coefficient of 0.10 and four cushioning materials A'with a loss coefficient of 0.30 were used. , Η = (0.10 × 5 + 0.30 × 4) / (5 + 4). According to Table 3, the set of FIGS. 11A and 11B has the same dynamic spring constant of the cushioning material 31, but the loss coefficient of the cushioning material 31 in the set of FIG. 11A is 0. In the set of FIG. 11A using the cushioning materials A and A'with different loss coefficients, the loss coefficient of the cushioning material 31 is as high as 0.19.

FIG. 12 shows the transmission characteristics based on the loss coefficient of the cushioning material 31 of each set of FIGS. 11A and 11B. According to this, the set of FIG. 11 (a) having a loss coefficient of 0.19 for the cushioning material 31 has an anti-vibration effect as compared with the set of FIG. 11 (a) having a loss coefficient of 0.10 for the cushioning material 31. It can be seen that (vibration reduction factor in the high frequency range) is slightly inferior, but the damping performance is high (vibration amplification factor at resonance is lowered and vibration at the resonance frequency is suppressed).
Further, as shown in FIG. 11A, if the cushioning materials 31 having different loss coefficients are used in one set, the combination and number (ratio) of the cushioning materials 31 having different loss coefficients can be changed in one set.
