Description
Technical field
The invention belongs to earthquake simulation demonstration device, be specifically related to secondary wave analog demonstrator.
Background technology
Earthquake, claim again earthquake, vibrate, be the seismic wave that sharply breaks and produce that earth interior occurs, be recurrent a kind of spontaneous phenomenon on the earth.The movable sharp pounding that produces in the rock stratum at focus place when earthquake occurs, can produce that a kind of wherein a part passes to earth surface with the ripple that very fast speed is to all the winds propagated, Here it is seismic event.The circulation way of seismic event has three kinds: three kinds of compressional wave, shear wave and ground rolls, the direction of longitudinal-wave particle displacement is parallel with direction of wave travel.Compressional wave is translatory wave, arrives at first earthquake centre, and it makes ground that up-down vibration occur, destructive power a little less than.The particle displacement direction of shear wave is vertical with direction of wave travel, and shear wave is shearing wave, and it is second arrival earthquake centre, and it makes the shake of generation all around, ground, and destructive power is strong.Ground roll is the mixing ripple that compressional wave and shear wave excite generation after meeting in ground, and it is to propagate along ground surface, is to cause the strong principal element of destroying of buildings.Our country is the country of earthquake more than, annual because earthquake and dead number accounts for 55% of China's disaster death toll, thereby the earthquake ` that gets more and more people's extensive concerning.Due to the singularity of earthquake disaster, let us can not be had gained some understanding intuitively, understanding earthquake that can not be correct to earthquake disaster.Although earthquake is irresistible; but as long as the knowledge of the grasp that the public can be correct reply earthquake disaster; for saving life and protection property safety, still there is positive meaning, also there is no a kind of analog demonstrator that can show intuitively secondary wave moving situation at present.
Summary of the invention
The object of this invention is to provide a kind of simple in structurely, can intuitively show the secondary wave analog demonstrator of shear wave propagation when earthquake occurs.
A kind of secondary wave analog demonstrator of the present invention, comprising: optical axis, handwheel, the first end cap and the second end cap, and wherein, one end of optical axis and the second end cap are affixed, and are connected with handwheel by handwheel auxiliary section; The other end of optical axis and the first end cap are affixed, and the first end cap is connected with optical axis fixed part, spring straining portion, Wire pulling portion, steel wire fastening part successively by connecting link, between Wire pulling portion and spring straining portion, by extension spring, are connected; And on optical axis, be serially connected with several with the particle web member of handle ball web member, between adjacent particle web member, be provided with successively plane ball bearing and without oil jacket, wire rope links together particle web member successively, and wire rope one end is connected with Wire pulling portion with the affixed other end in optical axis auxiliary section.The first end cap and the second end cap are affixed with plexiglass tent respectively.
Adopt technique scheme, all particles are fixed on a major axis and can sway, between particle, by elastic wire rope, link together, steel wire one end hangs extension spring one end and is fixed on handle, external force drives handwheel rotation, wire rope, along with handle is out of shape, forces extension spring to draw high distortion, according to the transfer principle of power, drives particle vibration.Because particle is fixed on a major axis, can sway, particle is subject to External Force Acting to be broken inherent balance state and vibrates near equilibrium position, the place that every power passes to, and each particle vibrates near the equilibrium position of oneself.Because power is propagated forward with limited speed, the particle that later starts vibration falls behind a period of time in step than the particle that first starts vibration, has a phasic difference.The propagation of power on particle, forms a kind of " heaving of the sea " in appearance, forms crest and trough, the just vibrational state of propagation, and the particle of medium does not enter with wavefront.Thereby realize the vibrational state that Simulating Transverse Wave is propagated particle.
In sum, the invention has the beneficial effects as follows: adopt the Simple earthquake shear wave analog demonstrator of technique scheme simple in structure, cheap, by change, drive the size of external force, this device can be demonstrated particle more intuitively in wavelength, the cycle of the lower formation shear wave of different frequency, therefore the present invention's image, demonstrated secondary wave moving situation and disaster prevention knowledge intuitively, can improve the consciousness that masses prevent and reduce natural disasters.
