Yakumo Corporation (Headquarters: Shinagawa-ku, Tokyo; President: Hideyuki Funaki) has developed a new product, "Dual AMD," which enables vibration control in two horizontal directions with a single unit as a wind vibration countermeasure for high-rise buildings. The new product will be exhibited at the 17th Vibration Technology Expo to be held at Pacifico Yokohama on February 5 and 6, 2026.
In addition, the importance of vibration control technology and its impact on occupant performance will be introduced using a "horizontal vibration simulator" and a miniature AMD model.
*The Vibration Technology Expo, organized by the Vibration Technology Expo Executive Committee, is a technical exhibition specializing in providing the latest information on all types of vibration generation, vibration isolation, vibration control, vibration elimination and applied technologies in the industrial world.

■Exhibition Overview
- First display of the new "Dual AMD" product
We will introduce our new product, Dual AMD (Active Mass Damper for High-rise Buildings), developed as a wind sway countermeasure for high-rise buildings, at our booth.
Dual AMD is a vibration control device that can operate in two directions (XY and Y) with a single unit, saving space and cost compared to conventional vibration control systems.
Main features of Dual AMD
Vibration control in two XY directions (two horizontal directions) with a single unit
High vibration damping effect by large mass weight of 50~100t
Large stroke of ±950mm
2-divided frame structure improves workability
Program control tailored to building characteristics

- Experience wind shaking with the popular "Horizontal Vibration Simulator
The "Horizontal Vibration Simulator," which was well received by many visitors last year, will be set up again this year.
This device allows visitors to experience the wind sway that occurs in actual buildings, such as skyscrapers and slender mid-rise buildings, at the venue. By comparing the results with the Building Society of Japan's occupant performance evaluation standards, visitors can get a feel for how much swaying affects the human body.
Unlike earthquakes, wind-induced shaking is characterized by long-lasting duration. As a result, they can cause a sense of uneasiness about the building and motion sickness-like symptoms, which can greatly affect the quality of life of the occupants. The importance of these issues can be realized through the sensory device.
Experiential situations: wind sway and vibration in low to mid-rise buildings
Max. number of passengers: 1
Ages: 10 years and up

[On the issue of wind sway in skyscrapers.
Recent trends have seen an increase in the number of super high-rise buildings and long, narrow mid-rise buildings on narrow lots. Due to their structure, these buildings are susceptible to wind-induced swaying, and the deterioration of their occupant performance has become a serious issue.
Unlike earthquakes, wind shaking continues for a long period of time as long as strong winds continue, causing the following problems
Increased anxiety about the building
Symptoms like motion sickness
Decrease in concentration and impact on operational efficiency
Decrease in resident satisfaction and increase in complaints
We provide integrated solutions to these issues, from survey and measurement to analysis, design, construction, and maintenance.
Our expert staff will also be available on the day to discuss other vibration issues.
