When the rod 39 is reciprocally moved through the second rail 61 and the second rail 61 is vibrated in the front-rear direction through the coupling member 40 provided at the end of the rod 39, the house 3 supported by the wheels 31 moves the first pair of rails 6 together. It vibrates in the front-back direction X along the direction.

The vertical vibration Z generated by the vertical vibration generating mechanism 25 of the house 3 is driven by the rotary shaft 38, and is rotated by the sprocket 46, 47 and the sprocket 48 fixed to the rotations 42, 43.
The rotating shaft is connected through the chains 50 and 51 that mesh with 49, respectively.
A pair of eccentric cams 52, 53 provided at both ends of 42, 43 are rotated. Since the eccentric cams 52 and 53 move the second rail 61 up and down via the sliding plates 54 and 55, the house 3 fixed to the second rail 61 vibrates vertically.

The second vibration generator 60 is mounted on a support base 64, and the support base 64 is mounted on the second rail 61 via small-diameter wheels 63, and the floor plate 62 in the house 3 is moved in the front-back direction U. , The horizontal direction V, and the vertical direction W.

First, the vibration of the floor plate 62 in the front-rear direction U is performed by the front-rear vibration generating mechanism 70. That is, by driving the hydraulic rocking cylinder 72, the turntable 73 fixed to the output shaft 72b is driven. Rotating plate 73 above

That is, by driving the hydraulic oscillating cylinder 92, the sprocket 93 fixed to its output shaft 92a is driven. And sprocket 9 through chains 99, 100
7 and 98 are driven to rotate the rotating shafts 95 and 96 and the eccentric cams 101 and 102 fixed to both ends thereof. The eccentric cams 101 and 102 are in sliding contact with sliding plates 103 and 104 fixed to the lower surface of the floor plate 62, and
Can be vibrated vertically.

Next, the hydraulic swing cylinder groups 33, 70, 81, 92
The operation of the hydraulic circuit that drives the valve with alternating hydraulic pressure will be described. The oil in the oil tank 23 is guided to the four-way switching valve 24 by the hydraulic pump 22 connected to the motor 21. For example, a hydraulic rocking cylinder
When the output shaft 33a of 33 is swung clockwise and counterclockwise, the four-way switching valve 24 is alternately switched between the a side and the b side. This switching operation is performed based on a command preprogrammed by control device 89.

When the four-way switching valve 24 is set to the side a, pressure oil is injected into the left chamber of the hydraulic rocking cylinder 33 through the check valve 88, and the vane 33d collides clockwise with the partition wall 33c. It rotates within the range. At this time, the pressure oil in the right chamber d is the check valve.
26, the flow rate is controlled by the variable throttle valve 27,
The swing speed of the output shaft 33a can be changed.

When the four-way switching valve 24 is switched to the b side, pressure oil enters the right chamber d side, and the vane 33d rotates counterclockwise by the same operation. Therefore, the hydraulic swing cylinder
33 is driven, and its output shaft 33a can rotate forward and backward to swing.

The first vibration generator constructed as described above
The vibrations generated by 30 and the second vibration generation device 60 obtain a complicated vibration pattern by changing the number of switching of the four-way switching valves connected to the hydraulic rocking cylinders 30, 70, 81, 92. be able to.

For example, as shown in FIG. 7, the longitudinal vibration composite wave has a relatively large first waveform generated by the first vibration generator 30 and a relatively large first waveform generated by the second vibration generator 60. Obtained by a small second waveform. Vertical direction
The vibration synthesis waveforms of Z and W are generated in the same manner as above.

The vibration in the left-right direction V is generated only by the second vibration generator 60 and the left-right vibration generation mechanism 80, but the combined vibration of the front-rear direction X and the combined vibrations of the up-down directions Z and W is synergistic. Thus, it is possible to obtain a synthetic vibration in a complicated three-dimensional space as a whole.

The first vibration generator constructed as described above
With respect to the vibrations generated by 30 and the second vibration generator 60, a complicated vibration pattern can be obtained by adjusting the rotation speed of each variable motor. For example, the combined vibration waveforms in the front-rear direction have a first vibration generating device 30 and a second vibration generating device 60.
Obtained by the relatively small second waveform generated by

Further, a vertical vibration waveform is generated in the same manner as above. The vibration in the left-right direction V is generated only by the second vibration generating device 60 and the left-right vibration generating mechanism 80, but due to the synergistic action of the combined vibration in the front-rear direction X and the combined vibration in the up-down directions Z and W, the entire vibration is generated. As a result, a composite vibration in a complicated three-dimensional section can be obtained.

If the number of swings of the hydraulic swing cylinder of each of the above devices is selected in accordance with a predetermined earthquake pattern, it is possible to obtain vibration waveforms in the front-rear, left-right and up-down directions. Furthermore, if you go one step further and use a personal computer as a control device, and program the number of swings of the hydraulic swing cylinder in accordance with a wide variety of seismic waveforms, a predetermined vibration pattern is called by an operator's command,
It is also possible to let a simulated person experience an actual earthquake.

[Effects of the Invention] As described above, the present invention is based on the first vibration generating device that uses the hydraulic oscillating cylinder as the power source and the hydraulic pressure generating device that generates the alternating hydraulic pressure in the hydraulic oscillating cylinder. Since the entire house is vibrated in the front-rear direction and the up-down direction, the floor surface in the house can be vibrated in the front-rear direction X and the up-down direction Z similarly to the house. Is also used as a power source to oscillate in the front-rear direction, the left-right direction, and the up-down direction by a second vibration generator that uses a hydraulic oscillating cylinder and a hydraulic oscillating device that generates an alternating hydraulic pressure in the hydraulic oscillating cylinder. Therefore, it is possible to obtain a vibration waveform in which various amplitudes and frequencies are combined and to vibrate the floor surface with the combined vibration waveform. It is possible to experience the earthquake of complex patterns close to the real thing in a simulated experience who are riding on the surface.
