摘要： A faulty bearing detection system provides means and methods for detecting a fault associated with a bearing. The fault detection system includes a vehicle with bearings and a computerized system to separate multiple vibrations from, chiefly the shaft, to identify the amount of faults in the bearings. The system converts mechanical information to electrical information, filters periodic signals for removal, filters background noise, and performs an energy ratio calculation for determining a potential fault condition and communicates the status of a bearing fault condition. By separating the bearing faulty impulse signals from the raw vibration signals, the bearing faulty signal-to-noise ratio is improved. Furthermore, by calculating the energy ratio between the bearing faulty signals and the periodic vibration signals, the loading effects added to the traditional bearing features are removed.

摘要： An apparatus for performing ultrasonic inspection of an object, during one measurement on the object, triggers a sequence of excitations of the probe system and receives a sequence of substantially identical echo signals reflected from the object, and further scales each echo signal to different degrees to increase and extend the dynamic range of the echo signals. An A/D converter is then used to digitize the scaled signal sequentially in a manner which dispenses the need for using numerous A/D converters and the associated filters. The digitized signal samples are then combined to produce a single digital output in a manner that is not over-flowed and with desirable resolution.

摘要： An ultrasonic probe issues an ultrasonic wave to an object, receives a reflected wave from an object, and is provided with multiple piezoelectric elements. A three-dimensional display section displays three-dimensional flaw detection data superimposed on three-dimensional shape data of an object. The computer acquires a reflected ultrasonic wave signal from a reference object (reference). Based on the acquired signal, the computer corrects a reflected ultrasonic wave signal acquired from another object having the same material and shape as the reference. The computer allows the three-dimensional display section to display three-dimensional flaw detection data generated from a reflected ultrasonic wave signal resulting from a difference between a reference and an object.
