Rubber Shock Absorber Characteristics & Applications:

As an important type of damping component, rubber shock absorbers have been widely used in various types of machinery, automobiles, railway locomotives, waterborne vehicles, aircraft and other aircraft. It can be said that rubber shock absorbers are required wherever vibration damping and vibration isolation are required. Rubber shock absorbers are so widely used because they effectively utilize the following characteristics of rubber:

1. Rubber has high elasticity and viscoelasticity;
2. Compared with the steel material, the elastic deformation of the rubber is large and the modulus of elasticity 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 beneficial to reduce impact deformation and dynamic deformation;
4. The stress-strain curve is an elliptical hysteresis line whose area is equal to the vibration energy (damping) that is converted into heat during each vibration period, which can be adjusted by formula design;
5. Rubber is an incompressible material (Poisson's ratio is 0.5);
6. The rubber shape can be freely selected, the hardness can be adjusted by the formula design, can meet the requirements of stiffness and strength in different directions.

Advantages Of Rubber Shock Absorbers:

1. The shape of the rubber shock absorber can be arbitrarily selected, so that the rigidity of the up, down, left and right, and front and rear directions can be obtained by reasonable design of the shock absorbing element, which can greatly simplify the structure of the shock absorber.
2. The rubber shock absorber has deformation characteristics in three directions, and allows for large errors during installation.
3. The rubber and metal can be firmly combined.
4. Because rubber has damping characteristics, the absorption vibration energy is converted into heat energy, and its vibration-absorbing ability is much larger than that of metal, especially suitable for high-frequency vibration.
5. The structure of the rubber shock absorber is simple, easy to use and maintain, almost no need to repair, no wear, no rust, no oil lubrication, not sensitive to the action of water and dust, no sudden damage during use, safe and reliable use. , low cost and long enough service life.
6. Can freely determine the shape, by adjusting the rubber formulation components to control the hardness, can meet the requirements of stiffness and strength in all directions; 7, internal friction is large, shock absorption effect is good, is conducive to cross the resonance zone, attenuate high-frequency vibration and Noise; 8, the modulus of elasticity is much smaller than that of metal, which can produce large elastic deformation; 9, no sliding part, easy to maintain;
7. Small quality, easy to install and disassemble.
8. The impact stiffness is higher than the static stiffness and dynamic stiffness, which is beneficial to impact deformation.

Application Of Rubber Shock Absorbers:

1. Rubber shock absorber for automobiles
2. Rubber shock absorbers for railway locomotives and railway sleeper pads
3. Rubber shock absorber for bridge
4. Rubber shock absorber for construction engineering

Since the rubber shock absorber has the above characteristics, it is widely used in the bogie of the running part of the locomotive. Rubber dampers for electric locomotives include centrally supported rubber cones, axle box tie rod elastomers, side bearing rubber piles, motor suspension rubber pads, elastic wheels, elastic gears, air springs, bow rubber blocks and ball joints for transmissions , coupler rubber bumper, etc.

The rubber shock absorber applied to the locomotive is mainly used to withstand compressive stress, shear stress and torsional moment, and to withstand two or more stress combinations at the same time. Various rubber shock absorbers have certain special properties and play an important role. The speed of railway locomotives continues to increase, and the dynamic effect on the line increases sharply, causing severe wear on the components of the line, the tires and the running parts of the locomotive. Therefore, the application of rubber shock absorbers is becoming more and more popular.
