摘要： A clamp for securing a transducer to a train rail comprises a bracket having a base (18) which engages the foot (16) of the rail. An upright arm (22) at one end of the base (18) extends adjacent the web (14) of the rail and carries a threaded adjuster (28) which engages the transducer (38) and urges it into contact with the rail. The clamp is sufficiently resilient so that, when the adjuster (28) is tightened to a predetermined extent, both temporary and permanent de formation of the rail can be accommodated without difficulty.

摘要： A method and system for implementing magnetostrictive sensor techniques for the nondestructive evaluation of pipeline structures. The system consists of a magnetostrictive sensor instrument unit, a data storage unit, and a plurality of magnetostrictive sensor probes are positioned on an in-line inspection vehicle. The instrumentation unit includes electronics for transmitting excitation pulses to a transmitting magnetostrictive sensor probe as well as electronics for amplifying and conditioning the signals detected by a receiving magnetostrictive sensor probe. The magnetostrictive sensor probes include both plate magnetostrictive sensors and permanent magnets which provide a DC bias magnetic field necessary for magnetostrictive sensor operation. The transmitting and receiving probes are attached to the in-line inspection vehicle by way of mechanical arms on opposing sides of the vehicle. The mechanical arms are spring loaded and are equipped with rollers which maintain the probes at approximately constant distances from the inside diameter of the pipe wall. The method involves generating pulses of shear horizontal waves of frequencies less than 200 kHz. The transmitting magnetostrictive sensor probe generates a wave that propagates in both directions around the circumference of the pipe wall and from a point adjacent to the transmitting probe. Both waves are thereafter received at the receiving probe spaced 180 degrees apart from the transmitting probe. Any defect present in the pipe wall within the circumference being investigated will show up in the received signal.

摘要： A method and apparatus is shown for implementing magnetostrictive sensor techniques for the nondestructive evaluation of plate type structures such as walls, vessels, enclosures, and the like. The system includes magnetostrictive sensors specifically designed for application in conjunction with plate typ structures or pipes that generate guided waves in the plates or pipes which travel therethrough in a direction parallel to the surface of the plate or pipe. Similarly structured sensors are positioned to detect the guided waves (both incident and reflected) and generate signals representative of the characteristics of the guided waves detected that are reflected from anomalies in the structure such as corrosion pits and cracks. The sensor structure is longitudinal in nature and generates a guided wave having a wavefront parallel to the longitudinal axis of the sensor, and which propagates in a direction perpendicular to the longitudinal axis of the sensor. The generated guided waves propagate in the plate within the path of the propagating wave. The reflected waves from these abnormalities are detected using a magnetostrictive sensor. Shear horizontal waves may also be created by rotating the magnetic bias 90 DEG and used for similar inspection techniques. Pipes, which act as curved plates, may also be inspected as well as electric resistance welds therein. In addition, steel sheet butt welds may be inspected with this technique.

摘要： A flaw detection system that uses a simple network configuration to find such a break as in a railway rail. A detector unit (20), relay units (30A, 30B) and a terminal unit (40) are arranged along a rail (11). An ultrasonic signal transmitted from the detector unit (20) through the rail (11) is relayed by the relay units (30A, 30B), and passed to the terminal unit (40). The ultrasonic signal received by the terminal unit (40) is returned to the detector unit (20) through the relay units (30A, 30B), and it is determined whether any break exists in the rail (11) based on the state of reception of the ultrasonic signal at the detector unit (20).

摘要： To distinguish between disruptions whose cause originates in a vehicle and those whose cause originates in a rail track on which said vehicle is moving the messages emitted by vehicle-mounted sensors for monitoring certain vehicle components are evaluated according to their chronological order. If the sensor messages propagate from sensor to sensor, the origins of the disruption are to be found at the level of the rail track. Sensor messages which can be attributed to only one or a few sensors and which occur repeatedly can indicate a disruption at the level of the corresponding vehicle component being monitored.
