Abstract
A wheel inspection system based on electromagnetic acoustic signals and having improved inspection by the use of a noise removing system and/or a pivotal mounting system. The invention also includes an improved detection head and data analysis.
Claims24
A wheel inspection system comprising:
- at least one electromagnetic acoustic transducer having a transmit coil to propagate an ultrasonic wave into a wheel and a receiving coil to receiving an ultrasonic surface wave from the wheel;
- a radio frequency generator for exciting the electromagnetic acoustic transducer and producing an ultrasonic wave in the wheel;
- a computer control unit connected to and communicating with the radio frequency generator and the electromagnetic acoustic transducer;
- a data acquisition unit connected to and in communication with the computer control unit and the electromagnetic acoustic transducer for determining and analyzing defects in the wheel;
- and
- a noise removing system to remove noise from the data.
3 more elements
A detection head for an electromagnetic acoustic transducer wheel inspection system, the detection head comprising:
- a housing for holding transducer components, the housing including a transducer pocket and a magnet pocket;
- a removable magnet assembly for removably mounting a magnet to the magnet pocket;
- and
- a removable transducer assembly for removably mounting a coil assembly of the transducer to the transducer pocket.
