摘要： An ultrasonic inspection technique may be used to inspect quality of a bond between thermal protection system (TPS) material and a composite. The technique may include a highly damped transducer emitting an incident wave, which may traverse through thermal protection system (TPS) material and to a back wall of a composite. The incident wave may be of a low frequency signal, and may return a bondline echo and a backwall echo. The bondline echo is returned when the incident wave reaches a bondline and the backwall echo is returned when the incident wave reaches the backwall of the composite. The bondline echo and the backwall echo may be used to generate a waveform to assess the bond quality, revealing possible unbonds or kissing unbonds.

摘要： A “periodic signal parameter” (PSP) indicates periodic patterns in an autocorrelated vibration waveform and potential faults in a monitored machine. The PSP is calculated based on statistical measures derived from an autocorrelation waveform and characteristics of an associated vibration waveform. The PSP provides an indication of periodicity and a generalization of potential fault, whereas characteristics of the associated waveform indicate severity. A “periodic information plot” (PIP) is derived from a vibration signal processed using two analysis techniques to produce two X-Y graphs of the signal data that share a common X-axis. The PIP is created by correlating the Y-values on the two graphs based on the corresponding X-value. The amplitudes of Y-values in the PIP is derived from the two source graphs by multiplication, taking a ratio, averaging, or keeping the maximum value.

摘要： A method for determining the starting instant (t0) of a periodically oscillating signal response (E2; E2′), wherein the signal response comprises a first set of half periods (E2a-d; E2′a-d) having a polarity equal to a polarity of the first half period (E2a; E2′a) in the signal response, and a second set of half periods (E2e-h; E2′e-h) having a polarity opposite to the polarity of the first half period (E2a; E2′a) in the signal response.The method comprises the steps of: determining a peak half period (E2e; E2′f) as the half period with the highest amplitude in a selected one of the first and second sets; determining a zero-crossing instant (ZC1; ZC′1) of the signal response occurring a known time distance from the peak half period (E2e; E2′f); determining the starting instant (t0) of the signal response (E2; E2′) based on the zero-crossing instant (ZC1; ZC′1) and a relationship between the peak half period (E2e; E2′f) and the starting instant (t0).
