Shock Absorber

Shock Absorber:

It is also called damper or insert,and Metal Absorber in some countries,to accelerate the attenuation frame and body vibration, to improve vehicle ride comfort.

When passing uneven road, although the shock absorption spring can filter road vibration, but the spring itself will have the reciprocating motion, and the shock absorber is used to inhibit this spring. The shock absorber is too soft, the body will jump up and down, the shock absorber is too hard will bring too much resistance, impede the normal work of the spring. In the modified process on the suspension system, shock absorber hard to collocation with hard spring, and spring the hardness and weight are closely related, so the heavier vehicles generally use the hard shock absorber and guiding device. The crankshaft torsional shock phase, to compete with the crankshaft (impact force by cylinder ignition and twist the crankshaft at Like).

Principle Of Operation:

The vehicle suspension system vibration due to the elastic element by the impact, in order to improve the ride comfort, suspension and elastic elements arranged in parallel for the attenuation of shock absorber, vibration, vehicle suspension system with shock absorber is hydraulic damper, its working principle is when the frame (or body) and between the axle vibration and relative rotation the shock absorber piston, move up and down, the oil shock absorber cavity will be repeated from one cavity through different pore flow into another cavity. The hole wall and the friction between oil and oil internal friction between the molecules of vibration damping force, so that the automobile vibration energy is converted into oil the heat absorbed by the shock absorber, and then emitted to the atmosphere. In the same oil channel section and factors such as damping force with the frame and the axle (or wheel) or the velocity of relative movement, and with oil viscosity.

Working conditions:

1. Room temperature 10 DEG -35 DEG range, relative humidity is less than 80%;

2. To be installed on a solid foundation or bench;

3. In the environment of absence from vibration;

4. The surrounding non corrosive medium;

5. The fluctuation range of the power supply voltage should not exceed the rated electric pressure + 10%;

6. The power of the testing machine should be grounded and reliable; frequency fluctuations should not exceed the rated frequency of 2%.
