HP-STAP Envelope Analysis Software is a vibration analysis module designed for early-stage bearing fault diagnosis. It helps you extract the envelope curve (also called the envelope spectrum analysis method) by connecting the maximum amplitude points across different frequencies, making weak defect signatures easier to spot.
| Earlier fault visibility | Enhances weak bearing defect features that are hard to see in normal FFT spectra |
|---|---|
| Envelope curve insight | Uses a spectrum-envelope approach (peak-connection across frequencies) to provide a clearer diagnostic view |
| Bearing-focused diagnosis | Built specifically as a dedicated method for early bearing fault detection, not a generic add-on |
| Faster decisions | Helps maintenance and reliability teams confirm abnormal patterns sooner with less trial-and-error |
Series: HP-STAP
Product Type: Envelope analysis / envelope spectrum analysis software
Core Purpose: Detect incipient bearing defects (early faults) from vibration signals
Key Method: Builds a spectrum envelope curve by linking peak amplitudes across frequency, supporting envelope-based vibration spectrum analysis
Envelope analysis is widely used when early bearing damage produces faint, repetitive impacts that may be buried under noise in a standard spectrum. HP-STAP focuses on this specialty method to highlight bearing-related fault features sooner, so maintenance teams can act before damage spreads.
Rotating machinery condition monitoring (motors, pumps, fans, gear-driven systems)
Predictive maintenance programs focused on rolling bearings
Troubleshooting abnormal vibration where standard spectrum analysis is inconclusive
Production lines requiring early warning before bearing failure affects output quality
(Kept general to avoid adding specs not shown in the image.)
Vibration signals typically collected from accelerometers (and other vibration transducers used in condition monitoring)
Supports envelope-based vibration spectrum analysis workflows where you compare trends and frequency-domain patterns for bearing diagnosis
(Configurable items vary by setup/licensing; below reflects typical envelope-analysis controls without inventing numeric specs.)
Envelope spectrum / spectrum envelope curve generation
Peak-amplitude tracking across frequency (envelope line creation)
Band selection / analysis range (for focusing on bearing-related frequency zones)
Result visualization: time waveform + spectrum/envelope plots (as shown in the software UI)
Data output: analysis results suitable for reporting/diagnostic records (export format depends on your software build)
Q1: What is “envelope analysis” in vibration diagnosis?
Envelope analysis is a vibration spectrum analysis approach that highlights repetitive impact-type features. In HP-STAP’s description, the spectrum envelope curve is formed by connecting the highest amplitude points across frequencies, making fault patterns easier to recognize.
Q2: Why is envelope analysis good for early bearing faults?
Early bearing defects often create weak, periodic impacts that can be masked in a regular spectrum. Envelope-based methods are commonly used to make those subtle features more visible—especially for early diagnosis.
Q3: Is this software only for bearings?
HP-STAP is positioned as a bearing early-fault diagnostic method, so it’s optimized for bearing-related signatures rather than being a general-purpose analysis tool.
Q4: What results should I expect to see?
You will typically see waveform and frequency-domain plots plus the envelope-related curve/analysis view, helping you identify abnormal bearing-related patterns earlier.
Q5: Can it be used in preventive maintenance programs?
Yes—envelope-focused bearing diagnostics are often used in predictive/preventive maintenance to reduce unplanned downtime.
