Undamped Vibration Absorption

[skaboy607]

I Have been studying a problem involving a two mass/spring system. I have been analysing the system and finding out the frequency at which the vibration of Mass 1 is absorbed by Mass 2 and spring 2. The problem can represent a quarter car system where Mass 1 is the unsprung mass (wheel, uprights, etc.) and Mass 2 is the car body. I am confused as I can't see why you would want a situation where the car body absorbs all the vibrations.

Any clarification that can be provided on this would be most appreciated.

Thanks

!In a quarter car system, it is desirable to have the car body absorb all the vibrations. This is because the car body is much more rigid than the unsprung mass and can therefore better absorb the energy of the vibration. By having the car body absorb the vibrations, it helps keep the vibration from transferring to other parts of the car, providing a smoother ride. In addition, it helps reduce wear and tear on the components of the car.
