POSITION STRAIN GAGE TABLES
|
EVENT#
| Event
Number corresponds to the sequential numbering of aircraft events
stored in the database
|
TINTERVAL
| Time
interval between data points. In seconds.
|
TSTART
| Start Time
(sec) at which valid record has been reduced and stored in the
database.
|
TEND
| End Time
(sec) at which valid record has been reduced and stored in the
database.
|
FILTERFREQ
| Frequency
of data collection for this event. In Hertz.
|
NPEAKS
| Number of
peaks identified in the record
|
OFFSETLEFT
| Baseline
value before aircraft strain induced could be detected by this
sensor. Baseline values change as a measurement of pavement response
to longer environmental conditions. Values are in micro-inch/inch.
|
OFFSETRIGHT
| Baseline
value after passage of the aircraft. In pure elastic mode,
offsetright Baseline values should equal offsetleft baseline values.
Values are in micro-inch/inch.
|
TIME1
| Time (sec)
of first peak.
|
PEAK1
| First peak
value (micro-inch/inch)
|
TIME2
| Time (sec)
of second peak (if present)
|
PEAK2
| Second
peak value (micro-inch/inch)
|
TIME3
| Time (sec)
of third peak (if present)
|
PEAK3
| Third peak
value (micro-inch/inch)
|
TIME4
| Time (sec)
of first peak (if present)
|
PEAK4
| Fourth
peak value (micro-inch/inch)
|
NOTE
