PlantAI Vibration Analysis “Vibra”
Vibration analysis, diagnosis and field balancing for turbines, generators, pumps, fans and motors: ISO severity zones, run-up plots, ranked fault causes and a balancing workbench.
PlantAI Vibration Analysis “Vibra” is a diagnostic workbench for rotating machinery. Load shaft-proximity or casing-accelerometer data, and it builds the standard plot set, rates every channel against ISO severity zones and ranks the probable causes with a recommended action. The same screen takes you into balancing: influence coefficients, one-shot and multi-plane solutions, and a PDF condition report to sign off. Every rule and formula is visible, so your Vibration Engineer can check the answer instead of trusting a black box.
What's inside.
Data Import
Upload CSV waveform exports or trend files from your monitoring system, map the columns to probes in one dialog, and convert units such as mils to µm on the way in.
Standard Plot Set
Waveform, spectrum, waterfall, orbit, Bode, polar, shaft centreline, full spectrum and bearing envelope, all from the same record.
ISO Severity Zones
Casing velocity to ISO 20816-3 and shaft relative displacement to ISO 7919 and ISO 20816-2, shown as zones A to D. Your OEM and site alarm limits can replace the defaults.
Critical Speed Finder
Critical speeds picked from run-up and coast-down data, with amplification factor, phase change and separation margin against operating speed.
Fault Diagnosis
Rule-based ranking of unbalance, misalignment, rub, oil whirl and whip, looseness, shaft bow, rolling-bearing defects, vane pass and electrical faults, each with its evidence, a confidence and a recommended action.
Balancing Workbench
Single-plane, four-run (no phase), and two-plane balancing with trial-weight sizing, hole-splitting for the weights you can fit, and an influence-coefficient library for one-shot balancing on the next outage.
PDF Condition Report
One click produces a report with machine data, limits, graphs, diagnosis with probable causes and remedies, the balancing solution and a sign-off block, under your company name.
Machine Simulator
A physics-based rotor and casing simulator generates run-ups and fault cases for training and for checking the balancing arithmetic before you go to site.
