referring to thread384-444725 about diesel enine frequency spectrum
(OP)
Hi,
I am trying to analyze hydraulic pressure frequency spectrum of a system driven by a diesel engine (V12, 4 stoke). I almost exactly see the frequency activity around 110-130 Hz as the picture in thread384-444725: Frequency from diesel engine that is also about diesel engine. I am wondering it is coming from engine or not? if so, I am sure it is not fundamental frequency. The rpm is almost 2000 and fundamental should be 200 Hz. However, I do not see that in frequency spectrum.
Thanks,

I'd expect the hydraulic pressure variations to be nominally related to the type of pump and engine rpm.
