Stage 02
Order analysis and separation
Shaft-synchronous analysis referenced to every load-carrying mesh, not just to one arbitrary shaft.
A gearbox under load is not one source. It is a dozen sources whose orders sit within a few percent of each other, and a single order spectrum referenced to one shaft smears most of them together. Resolving the measurement once per reference shaft — coherently, with the sidebands intact — is what turns a loud spectrum into a set of separable lines.
How it runs
- 01
Check the data
Angle reference present and clean, runs repeatable, speed range sufficient. Anything that fails here is reported before analysis time is spent on it.
- 02
Resolve per basis
One coherent order analysis per load-carrying mesh, so every line is read in the frame of the shaft that produced it.
- 03
Separate and quantify
Which lines are genuinely distinct, which are one excitation seen twice, and how well the data supports the distinction.
What it covers
- Gear mesh orders, their harmonics and the sidebands around them, resolved per reference shaft
- Overlapping excitations separated instead of averaged together
- Bearing and shaft signatures traced across the whole operating range
- Separation quality quantified per line, so a weak result is visible as weak
What you get
- Order spectra and spectrograms per reference shaft, with the mesh lines and sidebands labelled
- A table of the lines that are actually present, with the operating range each one holds in
- The analysis itself, reproducible from the stored parameters — not just pictures of it
What I need from you
- Measurement files with a usable shaft-angle or tacho channel
- Gear data for the train, so the expected orders can be derived
- The operating conditions of each run, as recorded rather than as intended
