Various vibration-dampening materials, such as metals, polymers, cement, and their composites. Due to their viscoelasticity, metals and polymers are the dominant materials.
Designing the interface of polymers, designing the microstructure of metals, and using admixtures in cement are the major components of damping improvement.
Rubber is the perfect material for applications requiring vibration dampening. It swiftly isolates vibration by absorbing energy and then releasing it as heat back into the environment.
Even though it lacks real dampening properties by itself, it can be an effective tool when combined with other materials. Rubber is a great material for absorbing vibration energy since it absorbs energy and releases it as heat while also having low vibration dampening effects.
In industrial, electrical, structural, and ergonomic applications where resonance and vibration are present, vibration dampening material is utilised to minimise or eliminate noise. Our viscoelastic polymer, Sorbothane, has been employed in a variety of products, including small appliances and protective footwear.
By altering the natural vibration frequency of the vibrating surface, damping materials reduce radiated noise while increasing transmission loss. Numerous items and applications are susceptible to vibration from both internal and external causes.
From a computer owner’s judgement of the quality of their noisy hard drive to the actual failure of a mechanical system as a result of high-cycle fatigue, the impact of this vibration can vary in severity.
The Global EV Vibration damping materials Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Electronics are susceptible to vibration from internal and external sources including shipment and unintentional drops. This includes laptop computers, mobile phones, automotive navigation systems, and many other forms of complex electronic equipment.
Since vibration is a frequent cause of damage to electronic connections and components, vibration dampening is an essential need when developing electronic systems. Soldering connections weakening, data loss or disk drive damage, inefficient operation, and performance are all causes for concern.
Vibration dampening is crucial with the popularity of mobile phones and PDAs like the iPhone and Blackberry since users frequently drop and mistreat them. Extreme shock must be well-handled by these gadgets. The selection of the best vibration damping substance for the task should come first.
When struck or activated by acoustic energy, thin metal components and structures easily transfer noise through natural resonance. With the proper vibration dampening substance, the issue of this vibrating metal can be easily resolved in many industrial and commercial applications.
Viscoelastic damping is the most popular damping technique used to handle vibration (and noise) issues. When a substance is viscoelastic, it demonstrates both elastic and viscous properties. When a load is applied, an elastic material stores energy; when the load is removed, all of the energy is released.
A viscous substance doesn’t produce any energy back. Once the load is removed, all energy is lost as “pure damping”. Therefore, during a load, a viscoelastic material stores some of the energy; the remaining energy is then released as heat.
