noris rubber vibration isolator Germany noris model noris price

noris rubber vibration isolators address the diverse vibration damping and noise reduction requirements of modern machinery. As an important category of damping components, rubber vibration isolators are widely used in various types of machinery, automobiles, railway locomotives, waterborne transport vehicles, aircraft, and other aerospace vehicles. It can be said that rubber vibration isolators are required wherever vibration damping and isolation are needed.

noris rubber vibration isolator features

The widespread use of rubber vibration isolators is due to their effective utilization of the following properties of rubber: 1) Rubber has high elasticity and viscoelasticity; 2) Compared with steel materials, rubber exhibits large elastic deformation and a small elastic modulus; 3) The impact stiffness of rubber is greater than its dynamic stiffness, and the dynamic stiffness is greater than its static stiffness, which helps reduce impact deformation and dynamic deformation; 4) The stress-strain curve is an elliptical hysteresis loop, whose area equals the vibrational energy converted into heat (damping) per vibration cycle, which can be adjusted through compound design; 5) Rubber is an incompressible material (Poisson's ratio is 0.5); 6) The shape of rubber can be freely selected, and hardness can be adjusted through compound design to meet stiffness and strength requirements in different directions.

noris rubber vibration isolator product classification

noris rubber vibration isolator characteristics and application areas

1) Shape can be freely determined, and hardness can be controlled by adjusting rubber compound ingredients to meet stiffness and strength requirements in all directions; (2) High internal friction provides good damping performance, facilitating passage through resonance zones and attenuation of high-frequency vibration and noise; (3) Elastic modulus is much smaller than that of metals, allowing for large elastic deformation; 4) No sliding parts, easy to maintain; 5) Low mass, convenient installation and disassembly. 6) Impact stiffness is higher than static and dynamic stiffness, beneficial for impact deformation. Application areas: Industrial rubber vibration isolators, automotive rubber vibration isolators, rubber vibration damping products for railway locomotives and railway sleeper pads, bridge rubber vibration isolators, construction engineering rubber vibration isolators.
