αGEL Solutions
Vibration Damping
αGEL’s exceptional vibration damping functionality, combined with highly soft physical properties, makes it far superior to conventional rubber dampers. αGEL dampers can be used in both sensitive precision components and large-scale machinery for low to high frequency vibrations. αGEL offers unique solutions for all of your vibration damping needs.
Characteristics
- ●Excellent Vibration Damping Functionality
- αGEL displays exceptional damping functionality (Loss Factor tanδ, etc.). Its high softness and pliability give αGEL this great vibration damping and vibration control performance.
- ●Silicone Vibration Dampers
- αGEL is a silicone-based material that combines softness and durability with a very low compression set. It can be used at a wide range of temperatures (-40°C - 200°C), resulting in unrivaled long-term reliability.
- ●Effective at Low Frequencies and
Ultra-Low Loads - αGEL products offer solutions for both small, sensitive parts and large-scale heavy machinery.αGEL excels in protecting parts from low frequency vibrations and effectively reduces vibrations at a wide range of frequencies.
- ●Custom Vibration Protection and Damping
Profiles - We employ over 30 years of experience in the field of vibration control to offer you a product with a customized size, hardness, and damping profile. We are happy to help you find the right product to meet your needs.
Application Example
By inserting αGEL between a vibration source and adjoining equipment/components, vibration transmission is reduced.
This protects the equipment/components and also reduces noise.
- Protection from outside vibration
- Protection from inside vibration
Mechanism
- Vibration damping
- Vibration damping is a method to reduce the number of vibration-associated malfunctions by mitigating vibration transmission. Taking vibration damping steps for motors, pumps, and other tremor-producing machinery reduces the extent of vibration transmitted to peripheral facilities, in turn cutting down vibration-related noise and vibration levels in surrounding areas and allowing for achieving a better environment. This approach is also effective in mitigating vibration coming from areas around vibration-sensitive machinery, but in such cases the approach is called vibration isolation to draw a distinction between vibration damping.
- The principle of vibration damping
(vibration isolation) - Provided below is the vibration transmitted to peripheral facilities when the machinery generating vibration has an elastic-body-supported structure: (See Figure A)
-
- τ：Vibration conductivity
- F：Vibration level transmitted to peripheral facilities
- F0：Vibration level of vibration-generating machinery
- f： Vibration frequency of vibration-generating machinery
- f0：Natural frequency of elastically supported machinery
-
- The ratio of f and f0 (f/f0) is called the frequency ratio. Figure B shows the frequency ratio and conductivity. Figure C indicates the relationship between the frequency ratio and vibration damping effect. Bringing down the natural frequency f0 is important in dampening wider frequency bands. Natural frequency f0 (Hz) can be expressed by the equation below. Either softening the elastic support material or increasing the weight of the vibration-generating machinery allows for reducing f0. (See Figure D)

- Vibration control
- Vibration damping (vibration isolation) is an effective approach to reducing vibration, but there may be no way to install vibration insulators in real usage conditions. In those situations, a technique called vibration control is harnessed to convert vibration energy into thermal energy, in turn suppressing vibration. Materials boasting a combination of damping properties and elasticity are called viscoelastic bodies, and the scale of damping properties regarding those bodies are expressed as a loss factor (tanδ). Materials with higher tanδ are considered to have better vibration control performance. (See Figure E)
