Looking at the data sheets for the Bruel & Kjaer 2635 it seems that as you say, it wouldn't be adequate. The displacement gain has already rolled off significantly at 1 hz.
I should explain that I've also been asked to measure lateral movement (~2 Hz) and vertical bounce (~1 hz) of the wagon...
I'm new to vibration analysis and I'm interested in measuring the dynamics of a rail vehicle.
I'm proposing to use a fibre optic gyroscope to measure roll acceleration (of approx 1 hz), but I need to be able to calculate roll displacement. I understand the usual method is to integrate...
