Quick Vibration Screening

Quick Vibration Screening

Fast health status assessment for rotating machinery. Produces a screening report in under 30 seconds with clear next-step recommendations.

Prerequisite: The predictive-maintenance-mcp MCP server must be connected.

Workflow

Step 1 — Signal Selection

Call list_stored_signals() or list_signals() to show available signals. If the user has not specified one, ask which signal to analyze. Load with load_signal(...) if needed.

Step 2 — Statistical Features

Call extract_features_from_signal(signal_id=...).

Report as bullet points:

• RMS: energy level
• Crest Factor: impulsiveness indicator
• Kurtosis: excess kurtosis (Fisher convention)
• Peak-to-Peak: overall vibration range

Step 3 — FFT Snapshot

Call analyze_fft(signal_id=...).

Report:

• Peak frequency and magnitude
• Top 3 spectral peaks (frequency + magnitude)
• Any obvious harmonic patterns

Step 4 — ISO 20816-3 Assessment

Call evaluate_iso_20816(signal_id=..., machine_group=2, support_type="rigid").

Report:

• RMS Velocity in mm/s
• Zone: A / B / C / D
• Severity description

Step 5 — Summary Card

Format the output as a concise screening card:

VIBRATION HEALTH SCREENING
===========================
Signal: {filename}
Overall: {Healthy / Monitor / Suspicious / Critical}

Key Indicators:
  RMS: {value}  |  CF: {value}  |  Kurt: {value}
  ISO Zone: {zone} ({severity})

Recommendation:
  {appropriate next step}

Decision logic:

ISO Zone	Kurtosis	Verdict	Recommendation
A	< 1	Healthy	No immediate concerns. Schedule routine monitoring.
B	1–3	Monitor	Elevated indicators. Schedule follow-up in 2–4 weeks.
C	3–6	Suspicious	Consider detailed bearing analysis (bearing-diagnosis skill).
D	> 6	Critical	Immediate detailed analysis recommended.

Important Notes

• This is a SCREENING tool, NOT a diagnostic tool
• Never make definitive fault claims from screening alone
• Always recommend targeted analysis for Suspicious/Critical results
• Use cautious language: "indicators suggest", not "confirmed fault"
• Confirm signal units with the user before ISO evaluation
