Next, the structure model manufacturing step (S30) is a step of manufacturing the structure model 200 to be installed on the upper part of the earthquake simulating means 100, that is, the upper part of the vibration plate 150, using recycled materials, a unit block manufacturing step (S32), the structure forming step (S34) and the truss structure forming step (S36) may include.

In more detail, the unit block manufacturing step (S32) is a unit block 210 that serves as a framework of the structure model 200 using recycled plastic bottles, plastic bottle caps 212a, 212b, and wooden sticks 216 or straws. As a step of manufacturing, first, the injection port 214 of the recycled PET bottle to which the lid 212a is coupled is cut in the horizontal direction, and then a through hole 212c is formed in the center of the lid 212a using an awl or the like.

After that, as shown in FIG. 3 , the lid 212b having a through hole 212c formed in the center portion similarly to the portion to which the lid 212a of the cut PET bottle inlet 214 is not coupled is further coupled. , the unit block 210 can be manufactured by cutting and combining the wooden bar 216 to a predetermined length in the through hole 212c formed in the additionally coupled lid 212b.

Conversely, the wooden bar 216 is cut to a certain length and coupled to the through hole 212c formed in the cap 212a of the cut PET bottle inlet 214, and the cap 212a of the cut PET bottle inlet 214 is coupled. It goes without saying that the unit block 210 can be manufactured by further coupling the lid 212b having the through-hole 212c formed thereon in the central portion that is not.

At this time, the lower end of the wooden bar 216 can be processed into a sharp shape to facilitate insertion into the through hole 212c, and is seated on the upper surface of the through hole 212c on the lower outer peripheral surface of the wooden bar 216 When the unit blocks 210 are connected to each other in a columnar shape by coupling the fixing ring 216a to a predetermined position, it may be configured to prevent a height difference with the neighboring columns from occurring.

In addition, although not shown, the wooden bar 216 is horizontally formed by additionally forming a through hole 212c in the portion of the PET bottle inlet 214 positioned between the two lids 212a and 212b forming the unit block 210 . It can also be configured to be installed as .

In addition, a straw may be used instead of the wooden rod 216 coupled to the through-hole 212c of the lids 212a and 212b, and the straw has less rigidity than the wooden rod 216, so the structure model 200 is relatively weak. ) can be used to prepare In addition, it is of course also possible to use other recyclables that can serve as a framework instead of the wooden bar 216 or straw.

Next, the structure forming step ( S34 ) is a step of connecting the manufactured unit blocks 210 to each other to form a structure shape. The unit block 210 adjacent to the lower end of the wooden bar 216 provided in the unit block 210 . ) of the wooden bar 216 is connected to each other in series by a method of coupling to the through-holes 212c formed in the lids 212a and 212b that are not coupled, thereby forming the pillar shape of the structure model 200 .

At this time, the height of the structure may vary depending on the number of connection of the unit blocks 210, and three or more pillar shapes may be manufactured to form the structure model 200 having a polygonal pillar shape, as shown in FIG. 4 . .

Next, the truss structure forming step (S36) is a step for forming the structure model 200 having a frame shape reinforced by the truss structure, and the two PET bottle caps 212a and 212b constituting the unit block 210) After winding the first velcro tape 220 on any one of the outer peripheral surfaces, as shown in FIG. 5, the second velcro in the diagonal direction between the first velcro tape 220 positioned on different layers of the neighboring pillars. A truss structure may be formed by connecting the tape 230 .

At this time, although not shown, the second velcro tape 230 may be horizontally connected between the first velcro tapes 220 positioned on the same layer of the neighboring pillars, and the PET bottle caps 212a, 212b Of course, it is also possible to form the truss structure by connecting and installing other linear recyclables other than the Velcro tape in an oblique direction while the double-sided tape is wound on the outer circumferential surface of ).

Next, the earthquake test step (S40) is a step of testing what kind of phenomenon occurs in the structure when an earthquake occurs using the earthquake simulation means 100 and the structure model 200, and the vibration plate of the earthquake simulation means 100 After installing the structure model 200 manufactured on the upper part (150), an experiment can be conducted by operating the vibration generating means 120 to observe what kind of phenomenon occurs in the structure model 200 .

In more detail, after installing a plurality of support members 154 for supporting the structure model 200 on the upper part of the vibration plate 150 at regular intervals, the unit blocks 210 are combined to form a column shape. The structure model 200 may be installed by inserting a wooden bar 216 or a straw provided at the bottom of the formed structure model 200 into the support member 154 .

At this time, the shape and size of the lateral cross-sectional area of the structure model 200 may be determined according to the number and spacing of the supporting members 154 installed on the vibrating plate 150, and the unit block 210 used for manufacturing the column shape ), the height of the structure model 200 may be determined according to the number.

In addition, the strength of the structure model 200 may be determined according to the type of frame shape used for manufacturing the unit block 210 , that is, whether a wooden rod 216 or a straw is used, and the shape and presence of a truss structure.

As described above, by operating the vibration generating means 120 of the earthquake simulating means 100 in a state in which the structure model 200 is installed on the vibration plate 150, the earthquake occurrence situation can be simulated, the intensity of the earthquake is weak, only the piezoelectric motor 122 installed on the vibration plate 150 is operated so that only relatively weak vibration is applied to the structure model 200, and a stepping motor 124 is used to simulate a relatively strong earthquake. By driving the slide member 136 coupled to the screw shaft 132 of the vibration transmitting means 130 to move forward and backward, the structure model installed on the upper part of the vibration plate 150 fixed to the upper part of the slide member 136 . A strong vibration can be transmitted to (200).

In this case, the intensity of the vibration caused by the driving of the stepping motor 124 may be set to various modes according to the source code programmed in the programming step S20 .

That is, as described above, the experimenter uses a mobile terminal in which the 'Arduino Bluetooth Controller' app is installed, and a control signal to drive a specific mode among the driving modes of the various stepping motors 124 programmed in the Arduino board 142. The generated control signal is transmitted to the Arduino board 142 through the Bluetooth receiver 148, and the Arduino board 142 controls the stepping motor 124 through the motor driver 144. The stepping motor 124 is driven according to the control signal generated by the experimenter so that the vibration of the desired intensity can be transmitted to the structure model 200 .

The following (Table 1) shows the seismic test results using the seismic test apparatus 10 according to the present invention, and the intensity of the earthquake is divided into four stages and, as shown in FIGS. 6 and 7, it is composed of a straight column structure. It is a result of performing an experiment on the structure model 200 and the structure model 200 including the truss structure, respectively.

The experiment is a method of observing the change of colored paper (CP) by generating vibration in a state that colored paper (CP) is placed on top of the structure model 200 manufactured by a combination of unit blocks 210 using a wooden bar 216 In the first step, only the piezoelectric motor 122 was driven to generate weak vibrations, and from the second step, the stepping motor 124 was driven to generate increasingly strong vibrations.

According to the experimental results, in the case of the straight column structure model 200, there was no change in the movement of the colored paper (CP) only in the 1st stage of vibration, the colored paper (CP) vibrated a lot in the 2nd stage, and in both the 3rd and 4th stages, the colored paper (CP) ) fell, but in the structure model 200 including the truss structure, there was no change in the movement of the colored paper (CP) in steps 1, 2, and 3, and the colored paper (CP) appeared to vibrate slightly only in the vibration step 4, so using the truss structure If the structure is reinforced, it can be confirmed that it can strongly withstand earthquakes.

Therefore, according to the seismic test apparatus 10 using the Arduino according to the present invention and the seismic test method using the same according to the present invention as described above, since it can be manufactured using commercially available products, the manufacturing cost is low, and the manufacturing cost is simple. In this way, you can easily experiment with various types of vibrations that can occur during an actual earthquake with various types of structures, make various unit blocks 210 using recycled materials, and create various types of structures through the combination of unit blocks 210. By allowing it to be freely manufactured, it is possible to effectively test the effect of vibration during earthquakes according to the shape of the structure, and the motor speed and operating time can be adjusted by simple changes in the Arduino program, so that the effect of vibration on the structure can be varied. It has various advantages such as being able to experiment.

Although the above-described embodiments have been described with respect to the most preferred examples of the present invention, it is not limited to the above-described embodiments, and it is apparent to those skilled in the art that various modifications are possible without departing from the technical spirit of the present invention.
