摘要： An impact tester includes a pendulum rotatable about a first axis from a latched position to an impact position. The pendulum is configured to impact a test specimen in the impact position. A safety return arm is rotatable about a second axis generally parallel to the first axis. The safety return arm is configured to lift the pendulum to the latched position, allow the pendulum to swing from the latched position toward the impact position, and selectively stop the pendulum between the latched position and the impact position.

摘要： The present invention features an apparatus and method for impact-echo testing of structures in situ, in the field. The impact-echo testing method provides a non-invasive, non-destructive way of determining the defects in the structure. The method is both uniform and reliable, the test procedure being substantially identical every time. The apparatus of the invention comprises a portable, hand-held unit having a plurality of impactors disposed therein. The plurality of impactors comprise a number of differently weighted spheres that are each designed to impart a different impact energy into the structure to be tested. Each sphere is disposed on a distal end of a spring-steel rod. A particular weighted sphere is chosen by a selector disposed on the testing unit. The sphere is withdrawn from the rest position by a pair of jaws to a given height above the structure. At a predetermined release point, the sphere is released, causing it to impact the structure with a specific duration and impart a given energy thereto. The impact produces stress waves that are reflected from the internal flaws and external surfaces of the structure. The reflected waves are detected by a transducer that converts the stress waves into an electrical signal (displacement waveform). The waveform is then processed to provide an amplitude spectrum, and in the case of plates, a reflection spectrum. For plates, the reflection spectrum can be interpreted by a neural network provides results that are indicative of either the thickness of the structure or of the defects disposed therein.

摘要： An impact test hammer includes a cylindrical handle having opposite first and second end portions and a hollow interior, a sensor portion fixed to the first end portion of the handle, and a grip portion fixed to the second end portion of the handle. An elastic striking portion is fixed to an outer periphery of the sensor storage portion, and an impact acceleration sensor is housed within the sensor storage portion for sensing a striking power of the elastic striking portion applied to a test object. A circuit is housed within the grip portion and operatively connected to the sensor by way of wiring extending through the hollow interior of the handle. Such a circuit includes a range switch, a scale conversion amplifier and a wind amplifier. A knob is provided on the outer periphery of the grip portion for operating the range switch to set a degree of amplification of the amplifier. The amplifier receives a signal from the sensor and amplifies the signal according to the amplification degree set by the range switch. The wind comparator outputs an indicator actuation signal when the output from the amplifier falls within a specified range which is determined based on the characteristics of the test object.

摘要： An impulse hammer of a variable sensitivity type permitting the user to instantly select from at least three different full scale operational ranges which includes an elongated handle having a plastic grip at one end and a head carried at its other end normal thereto. A head extender is detachable carried on one end of the head while a force sensor terminating in an impact tip is fixedly carried on the opposite end. An electrical circuit couples to a transducer in the force sensor and communicates through the head and handle with a coaxial connector located at the end of the handle. An impedance converter is included in the circuit transforming the high impedance signal from the transducer to a low impedance output voltage. A manual selector switch changes the voltage gain of the sensor to avoid amplification of noise level.

摘要： Apparatus and method for testing structures by impact. The structure is struck by an impactor associated with a force transducer the output of which is related to the force which the transducer experiences on impact and encompasses a frequency range including the lowest frequencies (typically approaching zero frequency, see FIG. 3) which that force contains to any substantial degree. A test spectrum of the force including that full range of frequencies is produced by a Fourier transformer in a form suitable for automatic comparison, and is then so compared with a reference spectrum typical of impact with a reference structure, and a signal is produced indicating fit or lack of fit between the test and reference spectra.
