Vibration Analysis with rpm instead of Hz and peak sum xyz
Posted: Sun 13. Dec 2015 21:01:45
Wintertime, perfect to have a closer look on the HW and played with vibration analysis. The tool is just great, thanks a lot.
My Wish:
RPM instead of Hz (rpm = Hz *60) on Axis,
General output with peak sum (xyz), allowing drill down into xyz on demand.
I did a vibration analysis and was impressed how easy I could get ridge of tail vibration.
rpm 2100 (35Hz) / Gear 8.85 (309Hz Motor) / Tail 4.8 (168Hz)
Took Main Blades of and released tail servos to move free.
I did start with a 60 Peak on Y-Axis
I did add some tape on one tail blade (around front edge in the middle/center), ending with 120 peak, so wrong blade.
Moving it to the other blade, got better results.
Making it smaller, thinks look great now.
