摘要:
A system includes a probe assembly configured to inspect components of an assembled flange connection when the probe assembly is disposed within a bore of the components. The probe assembly includes a shaft configured to be aligned with an axis of the assembled flange connection, one or more ultrasound probes coupled to the shaft, and one or more encoders. The one or more ultrasound probes are configured to interface with an interior surface of the bore of the components, to emit ultrasound signals into the components, and to receive ultrasound signals from the components. The one or more encoders are coupled to the shaft and are configured to determine a position of the one or more ultrasound probes relative to a reference point of the assembled flange connection during an inspection of components of the assembled flange connection.

This invention provides a method and device for nondestructive testing of an anchor bolt. Said method and device make it possible to quantitatively test the soundness of an anchor bolt affixed to a foundation via an adhesive anchor. In this method for nondestructive testing of an anchor bolt, in which the soundness of an anchor bolt affixed to a foundation via an adhesive anchor is tested, a section of the anchor bolt that is exposed from the surface of the foundation is hit so as to produce an impact noise, a signal waveform corresponding to said impact noise is received and subjected to frequency analysis so as to obtain frequency information for said signal waveform, and the soundness of the anchor bolt is nondestructively, quantitatively tested on the basis of said frequency information.

Generally, in accordance with one embodiment, a monitoring system comprises a sensor, a wireless tag, a reader and a notification apparatus. The sensor is correspondingly arranged in a structure. The wireless tag is a passive wireless tag which is correspondingly arranged in the structure to send identification information and measurement information of the sensor by using received electromagnetic wave as a drive source. The reader communicates with the wireless tag to acquire the identification information and the measurement information. The notification apparatus acquires the identification information and the measurement information from the reader, detects a wireless tag or a structure serving as a notification target based on the identification information and the measurement information, and notifies the notification target.
摘要:
An ultrasound measurement system and a method for carrying out ultrasound measurements is provided that includes a data acquisition unit and a transducer for coupling an ultrasound pulse into a connecting element and for extracting an ultrasound pulse echo from the connecting element. The ultrasound measurement system proposed according to the invention comprises the data acquisition unit which has a combination of analog and digital electronics for excitation and driving of the transducer. This is separated from a data processing unit and is in contact therewith via a wired or wireless connection.

Embodiments of techniques and technologies to verify the interference fit of fasteners are disclosed. In one embodiment, a transducer is positioned to transmit a shear ultrasonic signal through a region of a fastener which is subject to stress when the fastener experiences an interference fit. The shear ultrasonic signal is transmitted through a region of the fastener subject to the stress. As the transmitted ultrasonic signal encounters the region, it is mode converted corresponding to a degree of interference which the fastener is experiencing. A return ultrasonic signal from the fastener is received with the transducer. From the return ultrasonic signal, a processor determines the degree of interference fit which the fastener is experience and outputs an indication of the same.

摘要:
A method for evaluating installation of blind rivets including measuring the “cycle time” represented “y0”, transmitting sound waves through the blind rivet installed in the structure, measuring the “travel time” represented “x0”, relating “travel time” and “cycle time”, and obtaining a pair of times (x0,y0), providing a time relation pattern establishing a borderline between an area of suitable rivets and an area of unsuitable rivets, the border represented y=f(x), so for cycle time values greater than y=f(x), it is considered a “suitable area”, for cycle time values less than y=f(x), it is considered an “unsuitable area”, representing pair (x0,y0) in the graphic representation and verifying if the value of y0 is greater or less than the value of y=f(x0), classifying installation of the rivet as suitable or unsuitable according to the verification.

摘要:
A load indicating member is provided with an identifying element which can be accessed and used to determine ultrasonic measurement parameters specific to the load indicating member to provide more precise and more reliable load measurements by compensating for differences resulting from manufacturing variations in individual load indicating members. The parameters specific to the load indicating member can be stored in coding applied to the load indicating member or in a database that can be accessed remotely, for example, using the Internet.
