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