I’m aware that there is built-in vibration isolation for the IMUs on the Cube, but I suspect this isolation is optimized for the frequencies and amplitudes encountered on a drone. As some may recall from a year or two back, I’ve been experimenting with using the Cube as a flight data logger (not controller) for a manned ultralight airplane with a 25 hp two-stroke engine. I’d like to minimize errors due to the lower-frequency, higher-amplitude vibrations on this airframe.
I’m not a mechanical engineer, but my understanding is that if mount the Cube in such a way that the resonant vibrational frequency of the mounted system is much lower than that of the external vibrations, then the latter will largely get reflected away. What I don’t know is whether there are specific frequencies that would be mostly like to cause problems (e.g., the resonant frequency of the internal vibration isolation for the IMU). Any thoughts/ insights/suggestions will be appreciated.
