Damping and continual oscillation

[Zatie12]

Hi all,

I'm having trouble with damping and oscillation effect, especially with larger rockets.

Oscillation - the larger rockets (and they don't have to be absolutely enormous) will often sit on the pad and continually oscillatate/vibrate/"ripple". It's often impossible to time warp because the vehicle is apparently in motion. When in flight often this oscillation sometimes becomes uncontrollable and results in self disintegration.

Damping - two issues. Firstly related to above in the sense that the physics seems to get 'over excited' with larger vehicles. Secondly, the (A).S.A.S system seems to lack a dead zone, or needs more delicate control when close to target. If RCS is enabled practically any vehicle no matter big or small will turn to the designated target and then spam the RCS system left/right up/down continually, draining all of the propellant. I use MechJeb these days but it's the same problem with that addon too.

Any suggestions to solve these issues?

Thanks

Isn't this thread made for the "How to" section?

Add more struts. And then some more struts after that.

If your rocket is oscillating on the launchpad it is probably resting on the engines. Use launch clamps to raise the engine nozzles off the ground.

For the other problem Jokurr already made the correct suggestion: more struts!

I would suggest sticking SAS modules everywhere but they are hard to fit on 2.5 m parts.
