The use of rubber shock absorber: rubber shock absorber as an important damping element, rubber damper has a wide range of uses, has been widely used in all kinds of machinery, automobiles, railway locomotives, water transport vehicles, aircraft and other aircraft.

At present, it is mainly used for the following 4 aspects: 1, automotive rubber shock absorber 2, railway locomotive and railway sleeper cushion, rubber damping products 3, bridge rubber shock absorber 4, construction engineering.

The characteristics of rubber shock absorber rubber shock absorber: rubber shock absorber is widely used, has a long and high elasticity, and has good performance of vibration reduction, shock isolation and sound insulation. The shape and pressing convenience, can freely choose the shape and size, to meet the requirements of stiffness and strength; damping property is certain, can absorb the mechanical energy of high frequency vibration energy absorption is particularly prominent; the rubber material and the metal surface can be firmly bonded, so not only easy to manufacture and installation, but also can the use of multi-layer reduces the stiffness, changing its frequency range, low price. Absolutely perfect things do not exist, a rubber damper is not perfect, it also has some shortcomings, such as easily affected by temperature, oil, ozone, sunlight and chemical solvents, resulting in performance changes and aging, easy relaxation, so the life expectancy of about 8 years, but no more than life 10 years. The performance of rubber damper is related to the shape of rubber pad, formula and hardness, high hardness, large rigidity, large bearing, low hardness, low stiffness and small bearing capacity. The hardness of some rubber damping mats is divided into 40 degrees, 60 degrees C and 90 degrees C. It is necessary to pay attention to the selection of the rubber.
