EARTHQUAKE EXPERIMENT BOARD
TECHNICAL FIELD
Invention; enables scientists, industrialists and students to experiment and learn with real earthquake by entering data of earthquakes occurred in our world before or by entering data of any requests size of earthquake in a one to one simulation. PREVIOUS TECHNIC
Experiment boards produced with purpose of research and experiment form shakes via one-way or two-ways linear movements. Indeed earthquake formed P (primary) and S (secondary) waves constitute circular movements or ellipsoid movements in the earth's crust. Devastating impact on the buildings and elements on the earth stem from such circular movements. This situation caused by centrifugal forces impacting buildings. Conducting experiments with experiment sets forming linear motion is misleading because they cannot create actual effect.
It is likely that building materials made on the basis of this information claimed to be durable is also wrong.

DETAILED DESCRIPTION OF THE INVENTION
Invention consists of; lower chassis (1), sub-chassis top plate (2), the upper carcass (3), floor fixing plate (4), flag armrest(5), ground fixing stud (6), front piston connection plate (7), internally moving carcass (8), moving bottom sheet (9), piston joint connection (10), platform chassis (11 ), moving upper sheet (12), moving upper platform (13), piston (14), lower ball group (15) upper ball group (16), movable part (17), top cover (18) and outer frame profile (19) parts. Moving upper sheet (12) consists of oil set (12.1). The moving upper platform (13) consists of sheet metal (13.1 ).
Lower chassis plate (2) is connected to lower chassis (1) by welding. To secure earthquake experiment board to ground the bottom chassis (1 ) is connected with ground fixing plate (4) by welding. For increasing the strength of ground fixing plate (4) flag rest (5) is secured vertically between lower chassis (1) and ground fixing plate (4) by welding. There are suitable holes on ground fixing bolts (6) to be used for securing earthquake experiment board on ground fixing plate (4). Ground fixing bolts are screwed to these holes. Then upper carcass (3) is secured to lower chassis
sheet by screws, spot, smart screws or welding. Front piston connection plate (7) ensuring connection of piston (14) to top carcass (3) is mounted to top carcass (3). Lower balls group (15) is mounted in suitable intervals and pieces on lower chassis sheet (2).
In assembly of movable part (17), at least two pieces internal movable carcass (8) with sufficient space for the piston (14) to move in between and connected to joint connection (10) between them. First moving lower sheet (9) and then moving upper sheet containing oil set (12.1) are mounted to this assembly set. Suitable rate of oil is applied to section where lower balls group (15) and upper ball group (16) are located. There is an oil groove in which balls are put. Then platform chassis (11 ) is connected to internally moving carcass (8) by centering horizontally and vertically moving top sheet (12). Thus installation of moving section (17) is completed.
After the assembly process moving part (17) is placed on lower balls group (15). According to size of experiment board at least one piston (14) is secured to piston joint connection (10) on moving part (17) from side and front and then to piston front connection plate (7) on upper carcass (3). In continuation top balls group (16) is mounted on moving part (17). Top cover (18) is secured to upper carcass (3) by contacting to upper balls group (16).
In continuation of assembly operation is completed by mounting moving platform ( 3) to platform chassis (1 1) assembly.
Earthquake experiment board sampled in technical drawings as square can be designed according to different geometric shapes.
The operation of the earthquake experiment board is as follows:
Earthquake experiment board of which installation is completed is managed by a programmable logic controller (PLC) system. To run the system earthquake data covered by the scenario are entered into the PLC system. Algorithm of PLC system is designed uniquely.
For driving pistons in the system (14) there must be a hydraulic power unit. Experiment board where data are entered into the PLC system and hydraulic power unit is attached is ready and starts to work with the user's command.
Material and building to be experimented in accordance with the earthquake data entered as scenario is mounted on moving top platform (13). Motion of moving
top platform (13) acting as Earth's crust as a condition of scenario is calculated by the PLC system and applied. According to the calculated data, pistons (14) connected to moving part (17) are driven so as to create linear and circular movements in line with earthquake magnitude on lower balls group (15) and upper balls group (16) in accordance with axis. Process is repeated in accordance with the set time and magnitude. After completion data are reported by the software and archived.
