What's the point of suspension damping in the class file of a vehicle?

Does it affect a stability of a vehicle when running at high speeds? Does it make sense to use this parameter for the larger trucks, like Ural 375/4320?

@Rakoval500k Huh, it seems like no one knows anything about it...

It makes the truck bounce less, just like real shocks/dempers.
And if the demping is too high it will prevent your springs from doing there work and make it so it feels stiffer while you have soft springs.
