CYCOGS® brand, VCA TFA Vacuum Compression Apparatus, Thin Film Analyzer material technology testing platform
contain numerous sensors and additional sensors can be embedded.
Such additional sensors may include optical moisture content, moir'e optical pattern analyzers and other sensors that may be needed.
General Description
The VCA TFA is an advanced paper test instrument controlling relative humidity for testing and evaluating
mechanical properties of planar type materials.
Such materials include paper, plastics, corrugated, composites, textiles, elastomers, etc.
The load frame (load control) applies mechanical force and measures the resulting stress.
Extensometers provide strain data allowing data analysis of yield, energy, modulus and Poisson's ratio.
Sample measurements include load, and the X, Y, and Z deflections.
Dimensional stability test setup on paper with three extensometers.

Test Types
The tests can be conducted under various environmental conditions.
Relative humidity profiles include steady state, steady state plus steps,
square wave with ramp control (trapezoid), sine wave, saw-tooth (triangle) wave, swept frequency waves.
Custom profiles such as actual recorded data from a process or warehouse can be used.
The test types are as follows: |
|
|
Load |
|
Tensile, compression, creep, stiffness, biaxial (required biaxial test frame). |
Short column |
|
(Edgewise compressive corrugated fiberboard) (required short column fixtures). |
Dimensional stability |
|
(Four axis, X, Y, XY and Z). |
Moisture migration |
|
Curl, air permeability studies. |
Load test of plastic sample in tension.
Electronics
The TFA VCA has numerous subsystems.
The power is distributed through a high current sub-panel located in the utility cart.
The test unit also contains an uninterruptible power supply, computer and electronics.
Numerous sensors allow the real world to interface with the computer.
The computer is a current generation running Microsoft® Windows®.
The analog interface electronics uses 16-bit precision.
System Software
The Microsoft® Windows® based HMI (Human Machine Interface) software controls the TFA.
Concurrent multithreaded processes ensure high level of performance and self-monitoring.
The program running on Microsoft® Windows® is custom designed for this machine.
Basic data storage is in the form of an ASCII text comma separated values
(CSV) file that can be read by any software that can read a text file.
The custom software semi-automates sensor calibration.
Data can be played back with a second program using a similar screen for review or demonstrations.
Other Information
The internal load frame uses hydraulic clamps that are pressure adjustable.
The external load frame (biaxial) uses glue tabs.
The vacuum system provides sample restraint and air flow.
Maximum air flow results in minimal restraint.
The VCA TFA consists of two units.
The first component is called the Test Unit.
The second unit is called the Utility Cart.
The Utility Cart contains heat and noise generating devices such as motors, pumps, dehumidifier, etc.
that can be located remotely from the Test Unit.
The two units are connected with umbilical cables and pipes.
The separation distance between the two components depends on the application and the installation configuration.
