What material is best for damping?
Sorbothane is the best damping material for several reasons:
- It absorbs up to 95% of shock energy and more than 50% of vibration energy for millions of cycles;
- It performs across frequencies from 10 to 30,000 Hertz;
- It performs across temperatures from –20° to 160° Fahrenheit (–29° to 72° Celsius);
What is Sorbothane made of?
Sorbothane is a thermoset, polyether-based, polyurethane material. In addition to being viscoelastic, Sorbothane also has a very high damping coefficient. Sorbothane combines shock absorption, good memory, vibration isolation, and vibration damping characteristics.

What is Zeta in control system?
The damping ratio is a parameter, usually denoted by ζ (Greek letter zeta), that characterizes the frequency response of a second-order ordinary differential equation. It is particularly important in the study of control theory. Critically damped systems have a damping ratio of exactly 1, or at least very close to it.
What are the various types of damping?
2 Types of damping Types of damping are: viscous and hysteretic damping. Viscous damping depends on frequency. Hysteretic damping assumes non-linear relations between stress – deformations.
What is damping vibration?
Vibration damping is a term that’s used in industrial, electronic and ergonomic applications when there is a need to reduce the amount of energy that’s produced by the system. Normally engineers try to address and reduce this energy at its source so the disturbing force is not at or near a natural frequency.
How does rubber absorb vibration?
Rubber is used as vibration absorbers, because rubber has a relatively high shear modulus compared to other materials. That means when a rubber material is shear stressed, i.e. stressed parallel to its cross-section, rubber can be stressed more before it becomes permanently deformed.
What is material damping?
In the case of real structures some of this energy is lost per deformation cycles and this is called material damping. Damping is the conversion of mechanical energy of a vibrating structure into thermal energy. If we want to quantify the level of damping in a structure the absorbed energy per cycle must be determined.
What material absorbs kinetic?
Sorbothane® has been recognized as the highest performance, energy-absorbing material since 1982 and is recognized as the industry standard. Consider Sorbothane’s unique properties: A high tan delta value or damping coefficient. Absorbs more than 94% of shock energy.
How do I use Sorbothane on my keyboard?
The type of Sorbothane you should order: 30-40 durometer (lower is better)…Where you can place your Sorbothane:
- Between your keyboard’s PCB and plate.
- Between your case and PCB.
- On the exterior of your case (not recommended)
What is the most shock absorbing material?
Sorbothane
Sorbothane is the best solution when you need a shock absorbing material. Shock absorbing materials may also be called shock absorbing polymers, visco-elastic polymers, visco polymers or simply polymers. There are many other shock absorbent materials available like rubber, neoprene, silicone, etc.
When does resonance occur?
Resonance definition physics. Resonance occurs when the frequency of the applied force is equal to one of the natural frequencies of vibration of the forced or driven harmonic oscillator.
What is forced vibration and resonance?
Forced vibrations occur when the object is forced to vibrate at a particular frequency by a periodic input of force. If an object is being forced to vibrate at its natural frequency, resonance will occur and you will observe large amplitude vibrations.
What is the formula for resonance frequency?
The resonance frequency of each vibration can be found using the formula fn = (v/ λn) = (nv/2L). The term λn stands for (2L/n) and the term L represents (n (λn)/2).
What is resonance curve?
Definition of resonance curve. : a curve whose abscissas are frequencies lying near to and on both sides of the natural frequency of a vibrating system and whose ordinates are the corresponding amplitudes of the near-resonant vibrations.
