Over the years, people have constructed many great things like tall-castle buildings, bridges linking two places, and machines that contribute to our work processes. Yet, since they are natural disaster prone, particularly earthquakes, it is crucial that these buildings be strong enough to withstand such earthquakes. And what is an earthquake? — It occurs when the ground shakes violently. Shaking could cause the building to make weaken, sometimes the buildings could collapse which is very dangerous. This is where a technique called Table à secouer comes into play, the backbone of most safety systems used by scientists and engineers.
In order to make buildings safer and more resilient, we must understand how individual materials respond when seismic activity occurs. Various materials experience a multitude of behaviours when subjected to shaking. Certain materials can absorb shaking during vibrations and shatter when shaken violently. Researchers analyze these substances to see how they behave during motion aggressive enough to be interpreted as an earthquake. So that they select the optimum choice of materials to construct safe structures.
Because scientists need to know how their buildings will respond to earthquakes in order to build them to survive. This is a tool you use: shaker table → about the shaker table that is one of your special tools. It is like a huge flat plate or table that can move up and downwards, sidewards, and backwards and forwards. It is capable of simulating an earthquake's motions. On the shaker table, scientists will put models of building or machines, and then the shake is programmed to shake, vibrate like an earth quake. They can find out whether the models are strong enough to withstand an actual earthquake by observing how the models behave.
It is important to note that shaker tables are not just used to test buildings but also for the very important testing of airplane and rocket equipment. Shaker tablesSHaker table are extensively used in aerospace industry for verifying the dynamic behavior of various aircraft components under operational flight loads. As an example, you can mount jet engines on shaker tables and test to see if they are able to handle the vibrations and shaking when taking off and riding through the air. This sort of testing is significant because it helps make it sure that all gear is protected to make use of whilst flying excessive within the sky.
Shaker tables are also used to confirm the design of large machines that are used in factories or construction sites. At the same time, these machines need to be robust and tough enough to withstand the ground vibrations so they can operate safely and efficiently. Shaker tables are utilized to make various shaking patterns that replicate what these machines might experience in reality. This way, scientists can ensure the machines remain operational even during intense vibrations.
Over the years, the shakers table technology has been developed quite extensively, and scientists are continuously finding new & exciting ways to improve the performance even better. Nanyang JZJ developed an Intelligent Control System. It can active multidimensional vibration signals, up to 1024 channels! That is quite impressive as it enables scientists to perform extremely high precision tests. It makes the tests more efficient, therefore reducing the number of tests with useful information to scientists. With these emerging technologies, we will be able to continue improving the safety of our buildings and machines against earthquake hazards.
