1. Summary of Findings
Table 1 Summary of Analysis Results
#
Detection &
Trending
Data file name/number Comments
1
Consistent detection
on at least one signal
channel; i.e. the fault
indicators remain
consistently above the
threshold.
Day021_Hunting_SSA_2021120
8_105651.mat/4
Data reshaped to 4095 X 99 and averaged for 99 columns
(the result is going to be an array for each file). Maximum of
each array is concatenated into one array. The lower and
upper fence on IQR for each sensor is calculated and the
outliers detected. The earliest outlier is on the RF2 sensor on
the fourth file.
Figure 1 & Figure 3
2
Confirmed detection
on at least two signal
channels; i.e. the fault
indicators remain
consistently above the
threshold.

9_141330.mat/150
Data reshaped to 4095 X 99 and averaged for 99 columns
(the result is going to be an array for each file). Maximum of
each array is concatenated into one array. The lower and
upper fence on IQR for each sensor is calculated and the
outliers detected. The earliest outlier on multiple sensors is
on IP1,RF2, RL3, and RR4 sensor on the 15
th
file.

Clear multi-channel
indication of the
characteristic fault
features; i.e. faulty
planet gear meshing
with both the ring and
sun gears.

Confirmed trend of

consistent increasing
trend started from

Data reshaped to 4095 X 99 and averaged for 99 columns
(the result is going to be an array for each file). Maximum of
each array is concatenated into one array. The lower and
upper fence on IQR for each sensor is calculated and the
outliers detected. The point where the consistent increasing
trend start is on RF2 sensor on the 495
th
file.
