摘要： A transducer assembly is provided. The transducer assembly includes a magnetic portion, a body, a tensile pulse transmitter, and a pulse and current control unit. The magnetic portion is configured to provide a magnetic field. The body is disposed within an opening of the magnetic portion, and has a conductive portion configured to pass electric current near a body surface oriented toward the test surface. The tensile pulse transmitter is disposed within a cavity of the body and configured to transmit a tensile pulse into the test object. The pulse and current control unit is configured to control the tensile pulse transmitted by the tensile pulse transmitter, and to provide a current that passes through the conductive portion of the body and the test object, whereby a force urging the transducer assembly and the test object toward each other is generated responsive to the magnetic field and the current.

摘要： A method for initializing a chain of non-initialized data collectors is disclosed. The chain of non-initialized data collectors are coupled to a controller. In a first step communication between the controller and each data collector in the chain of non-initialized collectors is disabled, except for an active non-initialized data collector, The active non-initialized collector is coupled to the controller and any remaining non-initialized data collectors. Next, the active non-initialized data collector is initialized by assigning an identification number to the active non-initialized data collectors. The active non-initialized collector becomes an initialized data collector. Then, communication is restored between the initialized data collector and a next active non-initialized data collector in the chain of non-initialized data collectors. The method repeats until all non-initialized data collectors are initialized.

摘要： A system for detecting the onset of structural failure in a structural element subject to a mechanical load comprises a metering array, a signal processor, and an output processor. The metering array measures physical quantities associated with the structural element. The signal processor transforms the measured physical quantities into a series of sample mode spectra, and the output processor generates output as a function of the series of sample mode spectra. Methods are also disclosed for detecting the onset of failure in a structural element subject to a mechanical load, for structural testing, and for structural health monitoring.

摘要： A method and/or an apparatus for determining the dynamic response of a microstructure is disclosed. A piezocomposite ultrasonic transducer device formed of a piezoelectric material and a polymer material around said piezoelectric ceramic material is used to provide a pulsed bulk acoustic wave having a bandwidth of at least 20% to excite a microstructure. The microstructure is attached onto the transducer, and the pulsed bulk acoustic wave generated through the transducer in response to a pulse voltage excites the microstructure to vibrate. Meanwhile, the dynamic response of the microstructure can be monitored by a laser Doppler vibrometer, and shown by an oscilloscope.
