Rubber Damper Has a Great Damper Effect

Rubber is characterized by both high elasticity and high viscosity. The elasticity of rubber is produced by the changes in the conformation of its crimped molecules. The interplay of rubber molecules will impede the movement of the molecular chains and show the characteristics of stickiness, resulting in stress and strain are often in an imbalanced state. The crimped long-chain molecular structure of rubber and the weak secondary forces existing between molecules make the rubber material exhibit unique viscoelastic properties, and therefore has good damper, sound insulation, and cushioning properties. Rubber parts are widely used for vibration isolation and shock absorption because they have characteristics of hysteresis, damping and reversible deformation. In addition, rubber also has characteristics of hysteresis and internal friction, and they are usually represented by the loss factor. The greater the loss factor, the more obvious the damping and heat generation of the rubber, and the more obvious the damping effect. In summary, the rubber damper made of rubber also has a good damper effect.

The advantages of rubber damper:

(1) The shape can be freely determined, and the hardness can be controlled by adjusting the components of the rubber formulation, which can meet the requirements for stiffness and strength in all directions;
(2) The internal friction is large and the shock damper is good, which is favorable for crossing the resonance area and attenuating the vibration and noise of high frequency ;
(3) The modulus of elasticity is much smaller than that of metal, which can produce greater elastic deformation;
(4) No sliding part and easy to maintain;
(5) Small in quality, easy to install and disassemble.
(6) Impact stiffness is higher than static stiffness and dynamic stiffness, which is beneficial to impact deformation.
