Specific embodiment
As shown in Figure 1,2,3, 4, a kind of earthquake demo system, including top is provided with the housing 1 of opening, described housing 1 is internally provided with base 2, and the both sides of base 2 are provided with longitudinal carrier 3, and the inner side of longitudinal carrier 3 is installed with transverse direction Supporting table 4, the top between two cross-brace platforms 4 is provided with connection flat board 24, and the bottom for connecting flat board 24 passes through bottom bullet Spring 25 is connected with cross-brace platform 4, and the top for connecting flat board 24 is connected by top spring 23 with vibrations apparatus for demonstrating, The both sides for shaking apparatus for demonstrating are respectively arranged with the first motor 12 and the second motor 13, are set between connection flat board 24 and base 2 The 3rd motor 11 is equipped with, rotating seat 14 is mounted on the first motor 12, the second motor 13 and the 3rd motor 11, each rotating seat Rotation tabs 15 are mounted on 14.
Described vibrations apparatus for demonstrating includes being arranged on by top spring 23 first seismic mass on connection flat board 24 top 19th, the second seismic mass 20 and the 3rd seismic mass 21, are set between the first seismic mass 19, the second seismic mass 20 and the 3rd seismic mass 21 There is lateral connection spring 22, be respectively arranged with the outside of the first seismic mass 19 and the 3rd seismic mass 21 and matched with rotation tabs 15 The first groove 17 and the second groove 18 for closing.Described connection flat board 24 is T-shaped block structure, in the bottom of connection flat board 24 Centre position is provided with the 3rd groove 16 being engaged with the rotation tabs 15 on the outside rotating seat 14 of the 3rd motor 11, The length of connection flat board 24 bottom is not more than the distance between two cross-brace platforms 4.Electricity is installed with described base 2 Pond group 6, the first motor 12, the second motor 13 and the 3rd motor 11 are connected by wire with battery pack 6 respectively, and battery pack 6 is led to Cross wire to be connected with control box 5, the first motor switch 7, the second motor switch 8 and the 3rd motor are installed in control box 5 Switch 9, the bottom of the first motor switch 7, the second motor switch 8 and the 3rd motor switch 9 is provided with Sign Board 10.Described First groove 17 is arranged on the medium position in the outside of the first seismic mass 19, and the second described groove 18 is arranged on the 3rd seismic mass 21 The position of the middle part side in outside, the first motor 12 and the second motor 13 are separately mounted to two tops of longitudinal carrier 3.
This product concrete operations are as follows, and the circulation way of earthquake is understood first, and the seismic wave propagated in earth interior is referred to as Bulk wave, is divided into compressional wave and shear wave.The direction of vibration ripple consistent with the direction of propagation is compressional wave.Compressional wave from underground causes on ground Lower pitch.The direction of vibration ripple vertical with the direction of propagation is shear wave.Shear wave from underground can cause the level on ground to be shaken It is dynamic.Because compressional wave is more than shear wave in earth interior spread speed, so during earthquake, compressional wave always first reaches earth's surface, and shear wave is total Fall behind a step.So, when there is larger near earthquake, general people first feel to pitch, and just feel after spending the several seconds to more than ten seconds There is very strong horizontal jitter.Shear wave is the main cause for damaging.It is referred to as face ripple along the seismic wave of overland propagation, when bulk wave is arrived During up to roch layer interface or earth's surface, can produce along the very big ripple of the amplitude at interface or earth's surface propagation, referred to as face ripple.Surface wave propagation speed Less than shear wave, so following behind shear wave.
The system is developed aiming at the propagation characteristic of above-mentioned seismic wave, in demonstration, can integrally be put product Put in more smooth plane, then by controlling the first motor switch 7, the second motor switch 8 or the 3rd motor switch 9 real The operation of existing first motor 12, the second motor 13 or the 3rd motor 11, because the output end of each motor is mounted on rotating seat 14, rotation tabs 15, and the corresponding installation site of three rotation tabs of motor 15 are mounted on each rotating seat 14 It is upper to set fluted, in motor operation, contacted between rotation tabs 15 and groove, produce vibrations.In motor closed mode, Rotation tabs are with groove for contact is connected, it is ensured that vibrations can be produced in motor operation.
Specific wave band demonstration principle is as follows:When the first motor 12 is opened, the first motor 12 drives and is arranged on the first electricity Rotating seat 14 on machine 12 is rotated, and rotating seat 14 is rotated projection 15 and rotates, and rotation tabs 15 touch the first groove 17, first Groove 17 is arranged on the medium position of the lateral surface of the first seismic mass 19, therefore, when the first motor 12 runs, the first vibrating mass 19 start to do transverse movement, and imitate P wave dry run.The simulation P wave produced in the first vibrating mass 19 shakes After dynamic beginning, vibrations are broadcast to the second seismic mass 20 and the 3rd seismic mass 21 by lateral connection spring 22, in three seismic mass Between gap is set, the gap is presented irregular S character form structures end face, for demonstrate when P wave is produced each seismic mass it Between the degree that is squeezed, longitudinal wave propagation reach ground when people feel porpoising, object bob, demonstration true to nature go out compressional wave to shake The influence of the bottom surface that motion block is simulated.
When three motors 11 is opened, the 3rd motor 11 drives the rotating seat 14 on the 3rd motor 11 to rotate, and revolves Transposase 11 4 is rotated projection 15 and rotates, and rotation tabs 15 touch the 3rd groove 16, and the 3rd groove 16 is arranged on connection flat board 24 Bottom centre position, the 3rd motor 11 run when, connection flat board 24 start up and down reciprocatingly to shake, now, by bottom spring 25 and the elastic reaction of top spring 23, the bob of flat board 24 is connected, and drive first seismic mass 19, second on top to shake Block 20 and the vertical tremor of the 3rd seismic mass 21, simulate the effect of secondary wave, can be by observation, people's sense when shear wave reaches ground Feel is rocked, and object can swing back and forth, the influence for demonstrating out the bottom surface that shear wave is simulated to seismic mass true to nature.
On the basis of the above, the second motor 13 is opened, the second groove 18 is arranged on the middle part one in the outside of the 3rd seismic mass 21 The position of side, after the first motor and the 3rd motor is opened, can observe the propagation of face ripple by opening the 3rd motor, it is ensured that In the state of three motors are all opened, can produce along the very big face ripple of the amplitude at interface or earth's surface propagation, destructive strong, simulation is drilled Effect when showing that face rolling land shakes.
P wave and secondary wave can individually be demonstrated by this product, while can also be after compressional wave is demonstrated and then Demonstration shear wave and face ripple, comprehensive being simulated to earthquake are demonstrated, and convenient observation and research to earthquake facilitates intuitive The destruction that observation earthquake is caused.
