What Is Damping On Shocks?

How do you calculate the damping force of a shock absorber?

A displacement of the body is obtained by integrating the speed.

A reaction force of the spring is calculated by multiplying the displacement and a spring constant of the spring.

A damping force is calculated by subtracting the spring reaction force from the transmitted load..

How many types of shock absorbers are there?

Types of shock absorbers No matter the application, all shock absorbers fit into one of three broadly defined types conventional telescopic shock absorbers, struts or spring seat shocks.

What does compression damping do?

Compression damping regulates the force that moves a fork or shock through its travel. Compression damping is achieved with fluid, usually oil. This oil circulates through a compression circuit, and by restricting its flow, the suspension can be made firmer and can even be completely locked out.

Is a damper the same as a shock?

The proper name for shock absorbers is “damper” as it serves to dampen motion. While shock is absorbed by the spring, the damper functions to modulate the oscillations (bouncing). The unique feature of a damper is that its resistance to motion is proportional to how fast the motion occurs.

Which is better struts or shocks?

Well, shock absorbers usually give you better handling, while struts give you a lower initial cost for the vehicle. Now if you want to check these, and they should be checked on a regular basis, you’re going to do two things; number one you’re going to bounce the vehicle up and down, and you do that over each wheel.

How much does it cost to get a shock replace?

Shock Replacement Cost The average total cost to replace a pair of shocks will run about $250 to $580. An individual shock absorber will cost around $50 to $140 so parts alone will set you back between $100 and $280. A couple hours of labor to do the job is an additional $150 to $300.

How long do shock absorbers last?

five yearsThose variables make it virtually impossible to assign a number of years or miles as a broad stroke, though we would expect shock absorbers (or struts on vehicles with strut-type suspensions that incorporate the shocks into an assembly with springs and other suspension parts) to last at least four or five years unless …

Which is better gas or fluid type shock absorber?

Nitrogen gas is a cold gas, this means that besides not being flammable, keeps the shock absorber cooler than an oil shock absorber, been colder it will keep oil degradation by heat effect is reduced, making the shock absorber with gas a more durable shock absorber.

What are damping forces?

Damping, in physics, restraining of vibratory motion, such as mechanical oscillations, noise, and alternating electric currents, by dissipation of energy. Unless a child keeps pumping a swing, its motion dies down because of damping. Shock absorbers in automobiles and carpet pads are examples of damping devices.

How does a shock damper work?

A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated.

How do you calculate shock absorbers?

First, determine the amount of kinetic energy (EK) in the system. W = weight of moving mass, lbs. This equation represents the amount of kinetic energy that the shock absorber will convert to thermal energy each time it is impacted. S = stroke of the shock absorber, in.

How do I know when my shocks are bad?

The Warning SignsInstability at highway speeds. … Vehicle “tips” to one side in turns. … The front end dives more than expected during hard braking. … Rear-end squat during acceleration. … Tires bouncing excessively. … Unusual tire wear. … Leaking fluid on the exterior of shocks or struts.

What material are shock absorbers made from?

steelShock absorbers and dampers are generally made of high-strength steel to handle the pressures from the internal hydraulic forces. Elastomeric seals prevent the fluid from leaking out of the cylinder, and special plating and coatings keep the units protected from harsh operating environments.

How much shock travel do I need?

The amount of shock travel needed depends on the type of suspension you are working with (solid axle, or independent) so it is best to consider wheel travel as well. Most street driven vehicles should have a minimum of 2.5-3” of compression travel at the wheel and 2-2.5” of rebound travel as a good rule of thumb.
