shafTest system description
shafTest®
is a portable ultrasonic (UT) flaw detection system designed specifically to
improve upon current UT techniques and equipment used to monitor the condition
of large shafts and pins. Only a few highly skilled and experienced UT
inspectors can confidently assess the structural integrity of a complex shaft
by examining it in-situ from one end. The
shafTest®
system can verify the condition of a complex shaft without relying as heavily
on individual operators skill and experience.
shafTest®
achieves this by reproducibly collecting a 3D ultrasonic signature of a shaft
(V-scan), which can be stored for later retrieval and analysis. A
cross-sectional view of the shaft at any depth provides a clear visual
indication of the existence and extent of crack propagation. More importantly,
cross-sectional data from different measurements can be directly compared and
trended, with a graphical difference map indicating whether a crack has
progressed between two measurements.
A-scan
shafTest®
can operate in traditional A-scan flaw detector mode. All scan parameters are
software selectable and are saved with data to a database for retrieval and
analysis.
V-scan
V-Scan is a unique scanning mode where the end of the shaft is divided
into a grid pattern. A camera and tracking software allows the grid
position of the UT probe to be located. By storing A-scan information at each
grid location a complete ultrasonic volume map is constructed.
The V-scan analysis software automatically displays the total UT reflectivity as a
function of depth. This display highlights regions of interest (possible
defects) and provides tools to plot an ultrasonic cross-section through the
shaft at any depth by moving a slider along a simple schematic of the shaft.
By ensuring that V-scan data is always collected in a consistent and
reproducible manor it is possible to plot the difference between cross section
data collected from different measurements. In this way the progression of
crack growth can be visualised graphically and monitored.
3D-Analysis
In addition to displaying cross-sectional data, tools are provided to quickly
generate a 3D model of the shaft. The shaft can be viewed from any angle in
order to visualise the relative size and location of defects within the shaft.
