摘要： Methods for detecting and monitoring changes in mechanical structures and in walls of pipes, vessels and storage tanks, using muitimode acoustic signal propagation and detection, are described. Acoustic signals having chosen amplitude-time-frequency characteristics excite multiple modes in the structure under investigation, are generated and received at a small number of accessible locations, such as the ends of pipes and the tops and bottoms of vessels and storage tanks, with the inspection region between transmit and receive transducers. Small mechanical changes lead to acoustic scattering and attenuation among the various modes, which are detectable as changes in received signal intensity. Such changes may include material loss, material conversion and material addition. Once the structure is characterized in a known condition, the present method may be used to monitor the structure at a later time to determine whether changes have taken place. Methods for effective temperature compensation are also described. In addition, various pipe geometries and complex pipe geometries involving elbows, flanges, and the like can be monitored.

摘要： The invention relates to a method and device for ascertaining an edge layer characteristic of a component (12), in particular a component (12) for an aircraft engine. In the method, a reference body (22) with a known edge layer characteristic is arranged on the surface of the component (12). An ultrasonic wave (18) is introduced into the surfaces of the component (12) and the reference object (22) by an ultrasonic transmitter (16). An ultrasonic wave (18) resulting from the exchange between the component (12) and the reference body (22) is detected by an ultrasonic detector (20), and an edge layer characteristic of the component (12) is ascertained by an ascertaining device (28) using a difference between the generated ultrasonic wave (18) and the resulting ultrasonic wave (18).

摘要： A solution for evaluating the condition of a vehicle component based on resonant response profiles across a set of bands of vibrations. The vibrations can be induced into the target component during normal operation of the target component. The resonant response profile of the vehicle component can vary depending on wear or damage, and thus can be used to determine whether the vehicle component can safely remain in use. An embodiment comprises an isolated segment of rail of a length selected to allow a single railroad wheel on it at a time, with a set of devices which can induce specific vibrations into the wheel as it passes, and another set of devices which can acquire the resonance signals from the wheel.

摘要： A system and apparatus for detecting and monitoring cavitation inside a flow control device, such as a control valve, includes an acoustic emission sensor coupled to the flow control device in a manner to acquire acoustic signals caused by cavitation. A processor receives acoustic information from the acoustic emission sensor. The processor selectively identifies cavitation events from the acoustic information that meet certain predefined criteria. Cavitation levels are monitored based on at least one of a rate of cavitation events and intensity of individual cavitation events. The cavitation levels may be used to identify the presence of cavitation in the flow control device, to track accumulated cavitation in the flow control device, and/or to identify significant changes in the cavitation levels over time. This information may be used to reduce cavitation, estimate repair and maintenance, and/or monitor performance of the flow control device.

摘要： The present invention relates to a structural damage detection method for detecting damage of a structure. The method comprises scanning the surface of the structure with a tapper tapping with a tapping force at a predetermined frequency band while scanning; measuring the response signals transmitted from the surface of the structure; transforming the measured signals to acquire the signal spectrum at each position of the structure surface; intercepting from the signal spectrum a spectrum envelope; calculating a damage indicator at each position of the structure surface; and determining a position where the damage indicator changes abruptly as a position of structural damage. The present invention further relates to a structural damage detection system utilizing the structural damage detection method and a structural damage detection device for use therein.
