What is overdamped suspension?

An underdamped suspension (e.g., if there were no shocks on the car) would oscillate up and down for many cycles before settling down. So if your car is still bobbing two or three oscillations after a bump it is a bit underdamped. An overdamped suspension would have too much resistance to movement.

What does overdamped suspension feel like?

Overdamped will feel harsh on sharp impacts, seams in the pavement, and such. Any kind of bump where the wheels ‘want to get out of the way fast’, will feel harsh on an overdamped system. Damping slows suspension response. For best results, experience reality in moderation.

What do you mean by over damping?

over damping: the condition in which damping of an oscillator causes it to return to equilibrium without oscillating; oscillator moves more slowly toward equilibrium than in the critically damped system.

Are the shock absorbers in cars overdamped critically damped or Underdamped?

The automobile shock absorber is an example of a critically damped device. Additional damping causes the system to be overdamped, which may be desirable, as in some door closers. The vibrations of an underdamped system gradually taper off to zero. There are many types of mechanical damping.

Why are cars Underdamped?

This is caused by the shock pushing oil through small holes in the shock… move slow and oil flows fine, move fast and there is resistance. An underdamped suspension (e.g., if there were no shocks on the car) would oscillate up and down for many cycles before settling down.

Are shock absorbers Underdamped?

A car’s shock absorbers should be barely underdamped. If the car “bounces” once and then damps to zero when you push down on a fender and suddenly release it, the shocks are good. If it bounces three of four time the shocks are too underdamped and dangerous as you could lose control after a big bump.

Why is Overdamped bad?

An overdamped suspension would have too much resistance to movement. This is a bad thing because a suspension needs to keep the wheels in contact with the ground at all times.

Is damping good or bad?

Is Damping Beneficial or Harmful to my system? If your purpose is to get the ball rolling for a long time, then damping can obviously play against you… But if your purpose is to protect the system by attenuation the movement, then Damping can also be good!

Why is critical damping faster than Overdamped?

As with overdamping, a critically damped system does not oscillate, but it returns to equilibrium faster than an overdamped system. It also follows (approximately) the negative exponential, but with a larger value of λ, which allows it to return to equilibrium faster than an overdamped system.

What is Underdamped car?

An underdamped suspension (e.g., if there were no shocks on the car) would oscillate up and down for many cycles before settling down. So if your car is still bobbing two or three oscillations after a bump it is a bit underdamped.

What happens when a door damper is overdamped?

The spring is damped to control the rate at which the door closes. If the damper is strong enough, so that the spring is overdamped, then the door just settles back to the equilibrium position (i.e. the closed position) with­ out oscillating –which is usually what is wanted in this case. ..

What is the difference between under damped and over damped?

A system is called under damped, if damping ratio (denoted by zeta) is less than 1. A system is called over damped, if the damping ratio is greater than one, here system shows tendencies to achieve equilibrium without oscillating. Or you can say is is very much firm damping.

How to understand over damped under damped and critical damped in control system?

To understand over damped, under damped and Critical damped in control system, Let we take the closed loop transfer function in generic form and analysis that to find out different condition Over damped, underdamped and Critical damped in control system.

How much overdamping is acceptable in tuned dampers?

A moderate amount of overdamping might be desirable to achieve that. A textbook analysis of the step response of a system probably assumes the initial velocity is zero. Your question seems to be about single degree of freedom systems, and tuned dampers are basically 2 DOF systems.
