Damping characteristics of rubber:
The reason why rubber shock absorbers are so widely used is that
they effectively use the following characteristics of rubber:
1. Rubber has high elasticity and viscoelasticity;
2. Compared with the steel material, the rubber's deformation is
large and its modulus is small;
3. The impact stiffness of rubber is greater than the dynamic
stiffness, and the dynamic stiffness is greater than the static
stiffness, which is conducive to reducing the impact deformation
and dynamic deformation;
4, rubber shape can be freely chosen, hardness can be adjusted by
formula design, can meet the requirements of different directions
of stiffness and strength.
Introduction:
Rubber spring is a kind of high elastic body, made of ordinary
rubber material. The elastic modulus of rubber spring is small, and
the elastic deformation after load is large, so as to absorb shock
and vibration. It can be subjected to multiple loads at the same
time, but the high temperature resistance and oil resistance is
worse than the steel spring. If there are special requirements it
can be made of oil resistant rubber. The product has good vibration
reduction effect, small resonance field, long service life, low
cost, good cold resistance, excellent air tightness, waterproof,
electrical insulation, is the best choice for vibration reduction.
Rubber spring is mainly used in vibration machinery, double-decker
bus, truck and other industrial machinery, rubber spring is
commonly used in mechanical equipment, vehicle walking mechanism
and suspension, vibration reduction and buffering. The rubber
springs can also be designed into various structure forms according
to the work requirements.
