Active Vibration Control Device
AMD:Active Mass Damper
The active vibration control performance can be 3 to 4 times higher than that of the passive type. In terms of space, the same performance as the passive can be achieved in a smaller space.
Active Mechanisms
The active vibration damping device is a system that captures the vibration information of the building into a sensor. The servo motor then drives the weight based on a signal that is controlled in the opposite direction of the vibration that the building receives, reducing the vibration.
Horizontal Anti-vibration Control Device
Outline of traffic vibration disturbance in buildings
Buildings located near highways and elevated roads are prone to traffic vibration disturbances due to vehicle travel. This is because the vibration on the road propagates through the ground and amplifies the vibration in the horizontal natural period of the building. For this reason, even if you don't feel any vibration in a vacant lot, when you build a building, you will feel the rolling motion gradually increase as you go upstairs.
ωAD-H/ω2 Features
Although the damping effect varies depending on the vibration properties, a reduction effect of 1/3 to 1/4 can be expected. In addition, the control system, which is the heart of the system, is equipped with a high-performance compact active controller, which minimizes the mounting space and can be installed in existing buildings.

Vertical Anti-vibration Control Device
Mechanical Vibrational Measures
Vibrations from the production equipment cause vertical floor vibration problems. In some cases, the effect of equipment anti-vibration measures may not be sufficiently attainable. Work environments have been improved by suppressing the vertical vibration of floors with ωAD.
ωAD-120V Features
When the rotation speed of the production equipment is constantly variable, the ωAD-120V can support frequency tracking, which exerts a damping effect on the variable-forced vibration frequency.

Aerobics Vibration Disturbance Measures
Due to heightened awareness of health management, the number of buildings with aerobics and other sports facilities is increasing. Movements carried out in groups often vibrate more than expected, which can cause obstacles not only on the adjacent floors but also unexpectedly. It is often said that it is difficult for passive vibration control devices to deal with aerobic movements, because it's composed of the rhythmic jumps of dozens of people.
ωAD-V Features
This resonance system was constructed by supporting the operating mass with a metal coil spring. The result is increased efficiency and miniaturization.
For the drive system, we adopted the AC servo motor + ball screw system.
ωAD-V Mechanisms
The mechanisms of ωAD-V are basically the same as ωAD-H. The AD-H type is a horizontal drive, while the AD-V type is a vertical drive.
