Description

The present invention relates to a seismic isolation device that is supported by a support and supports the supported body.
In particular, the present invention relates to a seismic isolation mechanism composed of a guide member and a moving member having a moving body guided by the guide member.

In order to support an object on the basis of a support, a seismic isolation device may be provided between the support and the supported object that supports the object.
The seismic isolation device is composed of a plurality of seismic isolation mechanisms.
The seismic isolation mechanism is composed of a plurality of seismic isolation devices.
For example, a seismic isolation device that is supported by a foundation structure provided on the ground and supports a structure that is an object is provided.
By doing so, the acceleration generated in the structure when an earthquake occurs can be reduced.
In addition, the vibration source can reduce the vibration transmitted to the ground when the structure shakes.

For example, the seismic isolation mechanism is composed of a guide member having a guide rail forming a guide surface having a locus curved in an arc shape so as to be recessed downward, and a moving member having a moving body such as a wheel guided by the guide surface. It is composed.
For example, an X-axis seismic isolation mechanism that seismically isolates or suppresses acceleration in the X-axis direction may be combined with a Y-axis direction seismic isolation mechanism that seismically isolates or suppresses acceleration in the Y-axis direction.
Here, the X-axis and the Y-axis are virtual axes orthogonal to each other in the horizontal plane.
For example, the seismic isolation mechanism consists of a pair of left and right seismic isolation devices.

For example, a seismic isolation device has a moving body that moves in contact with a guide surface.
For example, a moving body is a wheel that rolls while being guided by a guide surface extending along the X axis.
For example, an arc-shaped locus recessed downward so as to have the deepest position, which is the deepest position in the center of each pair of front and rear sections, which are sections set so that the guide surfaces are arranged in series along the X axis. Is formed to have.
As the wheels move to each of them along the trajectory, a restoring force is generated to return to the deepest position as the wheel moves away from the deepest position along the X axis.
For example, a moving body is a wheel that is guided by a guide surface extending along the Y axis and rolls.
For example, an arc-shaped locus that is recessed downward so that each of the front and rear pairs of compartments, which are the compartments in which the guide surfaces are arranged in series along the Y axis, has the deepest position at the center. Is formed to have.
When the wheels move to each of them along the trajectory, a restoring force is generated so as to return to the deepest position as the wheel moves away from the deepest position along the Y axis.
As a result, a restoring force in the X-axis direction and a restoring force in the Y-axis direction act between the support and the supported body.
A frictional force is generated between the wheel and the rotating shaft or between the rotating shaft and the bearing. The seismic isolation mechanism acts as a resistance force when it moves along the X-axis and the Y-axis due to the frictional force. The resistance corresponds to the load supported by the seismic isolation mechanism.
When the trajectory changes, the restoring force changes and the seismic isolation damping characteristics change.

For example, the wheels are supported by a moving body support member by a rotating shaft.
When the wheel rolls on the guide surface, the friction material located between the wheel and the rotating shaft generates a frictional force.
As a result, a frictional force in the X-axis direction and a frictional force in the Y-axis direction act between the support and the supported body.
Here, the frictional force is proportional to the coefficient of friction between the friction material and the shaft hole of the wheel.
For example, the frictional force is a value obtained by multiplying the radial force acting on the wheel by the coefficient of friction.
Radial forces acting on multiple seismic isolation mechanisms support the supported object and the object to be placed on the supported object.
When the radial force acting on a plurality of seismic isolation mechanisms increases, the damping force generated in the seismic isolation mechanisms increases, and the seismic isolation damping characteristics change.

Furthermore, based on the above findings, the inventor examined seismic isolation devices, seismic isolation mechanisms, and seismic isolation devices that exhibit variations in seismic isolation characteristics such as a large damping force due to friction.
