“Analyse” module is created as a tool for vibration analyst user. It offers different analysis types and option to record findings as well as suggesting appropriate actions to the client. Can be accessed from the home screen by clicking “Analyse” from the “Analysis” section or from the menu on the left within the same section.
Analyse module is fragmented into three parts:
Header;
RMS trend and
Spectra.
Header includes following features:
Analysis type – select one option from “Single Spectrum”, “Multi Spectra”, “Multi points”, “Waveform”, “Waterfall” and “Comparison”;
Structure – tree structure for easy access to the required parameter;
Equipment – info on the equipment, task and parameter;
Notes – notes for the equipment and associated parameters;
Equipment library documents (XLS/X and PDF);
Analysis Summary – access to the module for writing findings and suggestions.
RMS Trend Graph presents trend of the RMS values for the collected data and includes following options:
Graph – presenting RMS values for selected processing methods (5). Data behind can be accessed by clicking on any of the points on the trend. By default, last data collected point is selected;
Point Measurements – List of all data collection for the selected point. Maximum number of different data collection per point is five. Measurement that is considered in the RMS trend and spectra below is ticked on the right side marked with “a” on the image. To change measurement considered to other measurement from the list just click on the target icon at the beginning of each row, marked with “b” on the image below;
Timeframe – Time span user want to review. This effects RMS trend;
Amplitude range – Two options are available automatic and custom. Automatic considers maximum and minimum RMS values collected for timeframe selected and sets the range while custom allows user to set them manually;
Processing methods – All available processing methods for selected parameter. They can be turned on or off by clicking on corresponding button.
Spectra section lists all spectra, associated waveforms and analysis options for selected processing methods. Each processing method (acceleration, velocity, demodulation) have horizontal segment where it outlines spectrum and cursor options.
Steps to analyse collected data by single cursor:
Select cursor type – Single Cursor;
Mark cursor on the spectrum
Click on the spectrum point;
Click on “Get from cursor” button – this sets 1xFreq from cursor;
Cursor can be added manually – add number in the text box and click on the “Manual entry” button;
“Locate Peak” – locates nearest highest point and interpolates frequency based on selected peak point. This frequency is set as 1xFreq.
By hovering over the spectrum with the mouse pointer cursor table is updated accordingly showing frequency, amplitude, order for location, hover and delta;
“Get default” button will bring default 1xFrequency for the equipment
“Show Top 10 Peaks” button will mark top 10 peaks on the spectrum and will present related info table under the “Move Cursor” functionality;
“Move Cursor” helps navigating with cursor in the spectrum. Inside controls will move cursor by one point in respective direction while outside controls will move it by five points
If “Show In Report” check box is ticked that spectrum will be present in the report;
Save icon grabs a print of the spectrum (including the cursors or zoomed in or out) and saves it as evidence for the corresponding analysis
Steps to analyse collected data by harmonic cursor (only different from single cursor):
Select cursor type – Harmonic Cursor;
Mark cursor on the spectrum
Click “Get from cursor” button
Set number of harmonics (default is 10)
Harmonics would be marked on the spectrum by orange dots
Table outlining harmonics details will be presented on the right
Steps to analyse collected data by sideband cursor (only different from single cursor):
Select cursor type – Sideband Cursor;
Mark central frequency on the spectrum
Click “Cursor” button next to the “Centre Freq.” text box
Mark delta on the spectrum
Click “Cursor” button next to the “Set Delta” text box
Set number of bands
Central frequency would be marked on the spectrum with vertical line
Bands would be marked on the spectrum with orange dots
Table outlining bands details will be presented on the right
Pending on the parameter settings (if waveform selected for collection or not) row waveform section is visible at the bottom of the analysis module. Here use can 1) listen waveform collected during recording. Option for 2) download is also available.
Condition Analysis
Condition Analysis or Analysis summary can be accessed from the header of the Analyse module by clicking on the “Analysis Summary” icon located on the top right corner.
This module can also be accessed from “Equipment Status” module and equipment page by clicking on the “Analysis Summary” icon in front of the equipment or on the right side respectively.
It is designed for analyst to write their analysis summary and propose actions to the client. Includes following features:
Drop down including past analysis, used to navigate through all equipment analysis;
Open a new analysis;
Analysis evidence – section to store all external document or images supporting user findings;
Equipment condition trend. Trend is clickable and used to in same manner as a top down box – to select (load) past analysis;
Timeframe dropdown linked to the condition trend;
“For measurements done” dates dropdown lists from-to dates when route was started and completed;
“Overall Values Summary Table” icon shows overall RMS values in a tabular format. If limits have been specified for the parameters they would be visible here in a traffic light system;
“Route Details” icon when clicked presents all information for the route analysed;
“Condition” dropdown outlines equipment condition for selected analysis instance;
“Analysis Summary” text box contains analyst findings and comments;
In “Proposed actions” area analyst suggests action/s to the client;
“Feedback” section is nominated for the client feedback related to the selected analysis or route;
