GERB Floating Bed Construction Demonstration

We will introduce a case where vertical vibration propagation was suppressed by a 1Hz floating floor!

We would like to introduce a case where a floating floor method was applied in the audience hall of a concert arena. In this facility, there are nearby apartments, schools, and hospitals, and if problems become apparent after completion, it could hinder operations. There were challenges in verifying and predicting vibration isolation effects in advance. Therefore, we designed and examined the project according to the site conditions, quantitatively predicting the vibration isolation effects through desk studies. We also provided on-site support during construction. [Challenges] - A music hall within a complex facility, adjacent to hotels and commercial establishments - Few vibration isolation measures targeting low frequencies (2-3Hz) - Insufficient effectiveness of vibration isolation using rubber materials *For more details, please download the PDF or feel free to contact us.

Introducing a case where a high vibration isolation effect was achieved using a gel floating floor!

We would like to introduce a case study applying floating floor construction methods at a fitness (dance studio). The facility was concerned about vibration transmission to the hotel within the same building, and due to height restrictions for the new building, it was necessary to reduce the floor height to secure the number of guest room floors for the hotel. Therefore, we implemented height reduction by embedding coil springs into the floating floor and conducted on-site vibration measurements to confirm the vibration isolation effect after construction. [Challenges] ■ High-level vibration isolation performance is required as a countermeasure for fitness vibrations. ■ Conventional vibration isolation using rubber materials would require increasing the floor height, necessitating the reduction of one floor from the hotel. *For more details, please download the PDF or feel free to contact us.

By using coil spring support to create a floating floor at 3-5 Hz, vibration transmission can be reliably suppressed!

We would like to introduce a case study of the floating floor method applied in a precision machinery manufacturing factory. In this factory, traffic vibrations from a nearby main road were occurring, leading to challenges in ensuring manufacturing quality and necessitating a high level of vibration isolation. As a response, we conducted on-site vibration measurements and considered countermeasures based on the results. We optimized the design and layout according to the specific conditions of the site. [Challenges] ■ The vibration isolation using conventional rubber materials was insufficient. ■ It was not possible to verify or predict the vibration isolation effect in advance. *For more details, please download the PDF or feel free to contact us.

[Free demo available] For vibration testing machines and vibration control measures for precision instruments. Achieves high vibration isolation in a compact space. Also prevents vibration transmission to the surroundings.

Our company proposes the "floating floor method" as a vibration isolation measure for vibration testing machines. By reducing losses during vibration testing due to low natural frequencies, it contributes to obtaining accurate test results. The space-saving design also allows for flexible adaptation to installation space constraints. Additionally, it can reduce natural frequencies from 2.5Hz to 7Hz, protecting work areas that are very sensitive to vibrations, such as those handling precision instruments, from mechanical vibrations and solid sounds. 【Features】 ■ High vibration isolation performance contributes to improved accuracy of vibration testing ■ Natural frequencies can be reduced from 2.5Hz to 7Hz ■ Space-saving design makes it easy to install even in limited spaces *For more details, please refer to the materials. Feel free to contact us. *Free demonstrations are available. If you wish to request one, please select "Request Demo" from the "Contact Us via Web" button.

On November 6th (Thursday) to 7th (Friday), 2025, we held the "Human Body Day 2025" at the NAC Image Technology Akasaka Multi-Purpose Space. We have uploaded videos of the highlights from each company and the presentations that took place on the day to our website. We encourage you to take a look. ---[Report on Human Body Day 2025 is here]------------------- https://info.nacinc.jp/jintaiday2025-report ------------------------------------------------------------------------- On the day of the event, participants were able to experience a wide range of products in a hands-on session format, including motion capture, force plates, eye tracking, and human body analysis software. We received numerous comments from attendees expressing high satisfaction, saying, "It was great to gain various information all at once," which makes us very happy. NAC Image Technology will continue to provide "valuable products to our customers." We hope you will join us for our next event as well.

The "Mechanical Stitch Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
