Hi guys after some extensive testing trying to see which way is the best to reduce vibration reaching the APM I am left to be lieve corrected in saying all efforts are useless ! below is a view views on raw sensors reporting back with different mounting methods of the APM.
First image is the control to compare everything to this was just with APM mounted to the copter with nylon nuts and bolts in the standard 3 holes provided
As you can expect you would see some vibration traveling back to the APM from the motors but nothing drematic.
Next test was done with the APM mounted on 3 nylon 20mm standoffs image below
The standoffs seems to increase the effect of vibration on the APM so not good.
Next Image was the APM mounted with the 3 nylon nuts and bolts agian but mounted on two pieces on 1mm tick velvet material.
Once again no real difference can be seen between results so I tried another well know method of mounting the APM ...Velcro!
Can you stop the difference ? last I tried a combination between the velvet material and velcro and this was the result below
......... I dont know what to make of this one . it seems like every different mounting method it effects a different Axil on the sensors so I geuss the trick is to find a mounting method to accomodate all sensors if that makes sence ?
I might also metion that I have tried , Cable ties, Sponge , Rubber mat as well all with the same results !
any of the Fathers of the ACM code know why this would be the case and if indeed unstopable is there a tolerance built into the ACM code base to ignore the values generated by vibration ?
