摘要： A method of detecting an internal flaw in a particulate filter includes a step of coupling ultrasonic transducer with the particulate filter. The method also includes a step of moving at least one of the ultrasonic transducer and the particulate filter relative to the other. Consistent coupling of the ultrasonic transducer with the particulate filter is maintained during the moving step. Ultrasonic energy is transmitted from the ultrasonic transducer through a majority of a volume of the particulate filter. The method also includes a step of determining if the particulate filter includes an internal flaw using the ultrasonic energy.

摘要： An on-machine inspection method for detecting whether a shaft of a transmission system has failed uses a test probe from flaw detection apparatus to discover echo signals with known peaks corresponding to defined weakened portions in the shaft. The test probe is then moved to prescribed angular distances about an end face of the shaft to obtain the echo signals.

摘要： A system for determining acceptability of torsional dampers for service in a machine system includes a fixture, an ultrasonic scanner and an indicating device configured to indicate at least one of acceptability and unacceptability of a torsional damper based upon receipt of a signal from the scanner. A nondestructive testing method for a torsional vibration damper includes scanning a torsional vibration damper with ultrasonic energy, and determining a test value for the damper indicative of a viscosity of fluid sealed within a housing of the damper based on receiving transmitted ultrasonic energy. Receipt of ultrasonic energy may be used to determine the flow rate of fluid within the damper by indicating a time for fluid to flow to fill a void within the damper. The system and method may be implemented in a remanufacturing or salvaging process for torsional vibration dampers.
