QTS-200 Machine & Structural Qualification Testing

Test Article Database

Each Test Article can have a variety of data stored for it in the archival Database;

• Multi-channel vibration and other data is acquired, post-processed and stored by ME’scope into the Database for each Test Article.  All data is archived in the Database as a snapshot with a date & time attached to it.  A snapshot can contain any of the following ME’scope data files; Monitored Shape Table, Animation Shape Table, up to three Data Blocks each containing multiple measurements.
• Monitored Shape Table. This table contains test parameter values that were post-processed by ME’scope. This ME’scope Shape Table can contain multiple shapes and shape components. Each shape component contains a test parameter. Each shape component can be trended in a Trend plot, and have Gauges and Pass/Fail Levels assigned to it.
• Pass/Fail Levels. Each test parameter can have up to six Pass/Fail Levels assigned to it.  Each Pass/Fail Level can have up to three positive values, (Alert, Alarm, & Abort), and three negative values.  Pass/Fail Level values can be defined either as absolute values (in engineering units), or as relative values (relative to Baseline values).
• Animation Shape Table. This table can contain ODS’s, mode shapes, or vibro-acoustic shapes. Shapes in this Table are displayed in animation on the 3D Test Article model in Console.
• Three Data Blocks. Up to three ME’scope Data Blocks can be archived for each Test Article in the Database. Each Data Block can contain multiple frequency domain, time domain, or Octave band measurements. ODS’s, mode shapes, or vibro-acoustic shapes can be displayed on the 3D Test Article model from a cursor position in the a Data Block.
• 3D Test Article model. A 3D model of each Test Article can also be stored in the Database. The 3D model can have test point Icons on it which depict the sensor locations on the Test Article. Hovering the mouse pointer of each Icon displays the gauge values and Pass/Fail Levels for the test point. The 3D model is also used for displayed shapes from the Animation Shape Table.
• Archive FIFOs. Each Test Article has four different First-In First-Out (FIFO) storage areas for storing snapshots of data; Short-Term, Long-Term, Pass/Fail Level Crossed Events, and User-Defined Events. The storage Rate & Length of the Short-Term & Long-Term FIFOs can be specified in minutes, hours, days, weeks, or the maximum rate possible. The Event Storage parameters include Number of Snapshots Before, Number of Snapshots After, and Total Number of Events to save in the FIFO.  All FIFO storage parameters can be changed “on the fly” during testing.

Qualification Testing Console Features

• Test Article Gallery. All Test Articles being are displayed in the Test Article Gallery. Each Test Article has status indicators including, time elapsed since last archive, surveillance camera live stream.
• Test Article Tree. All of the data for each Test Article is represented in a Test Article Tree Console. All data for a Test Article is conveniently displayed in graphics panels either by clicking on the data in the Test Article Tree or by dragging & dropping it onto a panel.
• Gauges. A Gauge can be assigned to each test parameter and displayed in Console. Each Gauge displays the current value, baseline value, and Pass/Fail Levels assigned to the Gauge.
• Event Log. When new data is archived in the Database from ME’scope, it is checked for Pass/Fail Level crossings by the Database service. All Pass/Fail Level crossings are logged as events in the Database, and displayed in the Event Log in Console.
• Email or Text Notification. Notifications of Pass/Fail Level crossings can be sent by email or cell phone text message by entering the appropriate email addresses and phone numbers into Console.
• Trend Plots. Archived parameter values can be displayed in a Trend plot in Console. A Trend plot shows the archived values of each test parameter. The horizontal time axis displays the time at which each parameter was archived.  Pass/Fail Levels assigned to each parameter can also be displayed together with the trended parameter values.
• Waterfall Plots. Data Blocks of spectra and time waveforms can also be archived as part of a snapshot. The measurements associated with a particular snapshot are displayed by clicking on the test data in a Trend plot. Measurements can also be displayed by clicking on them in the Test Article tree.
• Warning Bands. Multiple bands can be defined over frequency spans or time spans on each measurement. Each Gauge can have up to six Pass/Fail Levels assigned to it. This capability is particularly useful for detecting order-related vibration levels due to Test Article bearing faults, gear teeth faults, and other faults in rotating Test Articles.
• Interactive Shape Animation. If an Animation Shape Table is archived in the Database, ODS’s, mode shapes, or vibro-acoustic shapes can be displayed in animation on a 3D Test Article model.  Alternatively, shapes can be interactively animated from the cursor position in a Data Block.
• Hotkeys. Hotkeys can be defined to execute different macro-programs in ME’scope for each Test Article. All Hotkeys can be executed from Console to remotely control the execution of macro-programs in ME’scope.
