Looking for advanced helicopter vibration training

Has anyone taken a rigorous, data-driven rotor vibration diagnostics course beyond basic track-and-balance? I’m after CE that covers order analysis, Campbell diagrams, and HUMS fault codes with hands-on time (ACES 2020 or Vibrex 2000+), focused on driving down 1/rev and 4/rev to improve rotor efficiency — recommendations and provider experiences?

I had good results with ACES Systems’ advanced rotor smoothing workshop — order tracking, Campbell plots, and a full day on the 2020 with live runs to trim 1/rev and 4/rev; ask if you can bring your HUMS data for the lab. If you’re on Vibrex 2000+, the OEM/Chadwick‑Meggitt class maps fault codes to real faults better, though it’s pricier. “Bring your last 5 flights’ data” was the tip that made it click for us — what platform and HUMS are you on?

Parker Meggitt’s advanced Vibrex 2000+ course is solid for exactly this — Campbell diagrams, HUMS fault-code mapping, and live order tracking that let us push 1/rev and 4/rev down fast (less guess-and-shim, more data-and-trim). Small caveat: it’s tailored by airframe, so confirm your fleet and tooling; if you’re ACES-only, ask for an equivalency/crosswalk to 2020 workflows. Also ask if you can “bring your data logs” for the Campbell work so you practice on your own signatures.

I’ve found the ACES workshop particularly useful for those 1/rev challenges; did they cover real-time adjustments for HUMS too?
