What is the main working principle of Zhangheng ground motion instrument?

The working principle of Zhang Heng's geodynamic instrument is mainly based on the ancient theory of "waiting for qi", that is, the way of "the law of ash accounting", so it is called "waiting for the wind and geodynamic instrument". A large pillar is buried deep in the ground in the selected position, like the central pillar of the grass house when ancient people built houses, and this pillar is used to sense ** waves. In order to avoid the influence of the ground environment on the "capital column", hollow out the column at an appropriate depth, or dig the earth well first, and then bury the large column into compaction, and separate the column from the well wall at a considerable distance from the ground, so as to avoid the interference from the ground influence on the "capital column".

The top of the column shrinks to the top of a concave or hollow tube. A copper ball is placed on the top concave surface or hollow tube, and the diameter of the copper ball and the diameter of the top concave or hollow tube can be formulated according to the sensitivity needs, which overcomes the problem of friction coefficient in the production of "inverted column". A copper ball is placed at the top of the pillar, like a decorative ball at the top of the flagpole.

At the place where the "capital pillar" begins to shrink, 8 tracks stretch out in 8 directions: east, south, west, north, southeast, northwest, southwest, and northeast. When the buried capital column feels the propagation of ** wave in the formation, it will cause the capital column to produce corresponding displacement. The column is displaced, the copper ball located at the top of the column deviates from the center of gravity, falls off in the opposite direction of the force, and one of the eight tracks stretching out to different directions on the four sides of the column undertakes and guides to the corresponding direction, touches the dragon's mouth organ, and the copper ball contained in the dragon's mouth is spit out, so as to determine the direction of ****.

To sum up, Zhang Heng's creation of the wind and ground motion instrument is China's ancient detection instrument, but also the world's earliest instrument, it can not be the first, its role is only telemetry time and direction.

The invention of the ground motion instrument is based on a state of the surface to judge whether there is a **, so that it can play a role in predicting natural disasters in advance, which was a very advanced equipment at that time.

The main thing is to use the vibration principle of the top to make a ground motion instrument, this instrument is relatively accurate, but there is only a general direction.

In fact, according to some geographical structures, it is set up in a circle, and then when there is a vibration, the scene can be sensed through the vibration.

It was he who saw that animals could predict disasters in advance, so he came up with this idea and developed the geokinetic instrument.

The working principle is that this geodynamic instrument is placed on the ground, and when it occurs in other places, it will be transmitted to the geokinetic instrument through the vibration frequency collected on the ground, and the geokinetic instrument will drop the beads according to the direction it comes, so that it can predict **.

The principle of operation is that there will be some collisions between plates deep above the earth. Finally, propagation vibrations occur. ** waves will also appear. As long as the direction of the longitudinal wave texture is the same, the direction can be perpendicular.

The principle of work is that the ground ripple will be generated when the ground is generated, and the ground motion meter can sense the ground ripple, and then it can give a hint.

In general, the ground motion instrument works and operates according to the principle of inertia, and swings and hysteresis through inertia. Achieve the effect of running.

Zhang Heng's invention of the first instrument is the first instrument in human history, creating a new era of science. He is the pioneer of scientific research and the founder of science. His invention predates Europe by more than 1,700 years.

Zhang Heng shocked the world with the invention of the ** instrument and once again climbed to the peak of science. Presumably many people have heard of the ** instrument, which appears in our textbooks and is quite famous. And the ** instrument seems to be the magic weapon of the **** place of occurrence.

But since 2017, Zhang Heng's ** instrument has been officially removed from textbooks, which makes people wonder why the content from elementary school to university has been deleted again? Is there a problem with the ** instrument, or is there a problem with this part of the content?

The <>** instrument was invented by Zhang Heng, a scientist in the Eastern Han Dynasty. Its main function is to advance the time of occurrence and protect people's lives and property. It has a prominent historical role and is still respected by the people until now.

The most important role of the instrument is to accurately determine the location of the event in advance, so as to evacuate the local people and protect the safety of people's lives and property, which has a very prominent historical role. The founder of the instrument, scientist Zhang Heng is a native of the Eastern Han Dynasty, at that time, the occurrence of the instrument was more frequent, and he also had a lot of experience, so in order to grasp the dynamics of the country, he continued to study, and finally in 132 AD, he invented the world's first instrument - Hou Feng.

According to the "Book of the Later Han Dynasty", **Yi once detected **, but Luoyang did not feel ** at that time, which caused controversy. But a few days later, it was confirmed that ** happened in the Longxi area, and **Yi has been convincing since then. Zhang Heng.

Although there were many scientific and technological talents in ancient China, their scale is still small from the perspective of thousands of years of history. Zhang Heng, an astronomer and mathematician, inventor, geographer, and writer in the Eastern Han Dynasty, although his achievements are based on several"**Instrument"is the most famous, but in fact, his literary accomplishment is also very high, and he can be called four people with Sima Xiangru, Yangxiong, and Bangu, which is not something that ordinary people can do.

It can be very good to monitor when it is generated, and the sensitivity is extremely high, thousands of miles away, and the impact on future generations is also very large, which is a very effective thing.

The ground motion instrument can measure the direction of the occurrence, creating a new era of science, and the local occurrence can be prepared for earthquake prevention and disaster reduction in advance, which can greatly reduce the loss of the people.

It can detect **, can also detect the wind direction, can also detect the weather, can also ensure the safety of people's lives, and can also help people solve a lot of unnecessary troubles.

The general direction of the epicenter and the intensity of the epicenter can be taken in order to take precautions when the first comes, prepare the rescue work in advance, and reduce the number of personnel.

Zhang Heng paid great attention to the study of earth earthquakes, and created the world's first record-first instrument in 132 A.D. - ground motion instrument. Using it, you can not only know whether it has happened, but also measure the direction of its occurrence. In Europe, it was not until the 18th century that ** instruments were made.

After the geodynamic instrument was made, many people did not believe that it could measure**. In 38 A.D., the dragon's mouth placed in the Luoyang geodynamic instrument facing the west suddenly spit out a copper ball, which indicates that something happened somewhere in the west of Luoyang. But the people of Luoyang at that time did not feel **, so many scholars discussed it.

A few days later, Longxi County, more than a thousand miles west of Luoyang, sent people to Luoyang to report that ** had happened there. When the news spread, people were convinced by the high accuracy of the geodynamic instrument.

Why has the geodynamic instrument invented by Zhang Heng been deleted from history textbooks now? After reading it, I finally knew.

Analysis: The geodynamic instrument is made of fine copper, with a circle of eight feet, and the lid is raised, similar to a wine bottle. The surface is golden yellow, and there are eight golden dragons cast in the upper part, which lie in the east, west, south, north and northeast, southeast, northwest, and southwest directions.

The dragon is down, the dragon's head is downward, and the dragon's mouth is each holding a small copper ball, opposite to the toad squatting on the ground with its mouth open. Chongzen ground movement instrument cavity**, stand a copper pillar, thick at the top and thin at the bottom. The copper pillar is surrounded by eight crossbars, called "eight paths", each connected to a dragon head.

The copper pillar is a vibration device, and the eight channels are used to control and conduct the direction of the copper pillar's movement. When the geodynamic instrument is hit by the first wave, the copper pillar will fall to the direction of the occurrence, push the crossbar and the dragon head in the same direction, so that the dragon's mouth will open the stove, and the copper ball will fall into the toad's mouth, and make a sound to remind people to pay attention to the time and direction of the occurrence of the first and the first.

A bead is placed on the platform, and if you press it down slightly, the bead will roll in which direction. Or if we light a candle and put it on an uneven table, it will always fall to the lower side. The geodynamic instrument is designed according to these simple principles.

Ground motion can be transmitted to a long distance, but it is too far away for people to feel it, but the ground motion instrument can accurately measure and judge the hidden only.

However, Chinese scientists have determined that the working principle of the geodynamic instrument should be the "hanging pendulum principle", that is, the geokinetic instrument uses the inertia of a suspended cylinder to detect earthquakes, rather than simply erecting an upright pole at the bottom of the instrument as mentioned in today's history textbooks.

It's complicated. In general, the principle of inertia is utilized. It is to use an object fixed to the ground to hang a pendulum, the upper end and the ground quietly move, and the lower pendulum lags due to inertia.

Like a car jerking forward, the passenger leans backwards. The footsteps of this search and judgment are moving with the car, and the upper body of the person lags behind. And then push the tooth machine to act, separate, so that the dragon spits out pills.

At the same time, the energy of the dragon's jaw is used to drive the ingenious system to complete the stop of the pendulum and prevent malfunction. (Just done with a direction indication.) To restore the system, simply put the copper pellet into the dragon's mouth and close the dragon's jaw.

Since it requires people to move unconsciously, it is required to have a certain pendulum length. The longer the pendulum, the smaller the perception of the smaller **. (Not infinite, there is an optimal value).
