Re: [Paparazzi-devel] vibration filter

[gtoonstra]

The eco guys use a kitchen sponge for reducing vibs on the camera. I did some work on a gas heli here and it seems that a steel wire decoupling also helps significantly (pianowire). The diameter is determined by weight of equipment on top. It does really depend on the spektrum of frequencies that your vehicle generates. I have seen sandwiches of this wire decoupling on plywood, supported by a layer of sorbane or sorbothane (?) and then a really soft material like cheap foam earplugs. Zero vibs on an electric vehicle.

Hello friends, i finished 2 airframes this week.
One is a big 3m airplane and other is a 2.6m flywing.
This planes use gasoline engines.

In the flywing i using some vibration mount to help dump the vibration but its not absorbing all low frequency vibration when in idle speed.

I like know if any one tried some kind of filter to reduce the effects ofthis kind of vibration.
I see that some IMU have a MEDIAN_FILTER oprtion so i put this filter in drotek and tried it on my plane.

The result is very bad. It work better without filter.

So, anyone can help ?

kind regards.
