Abstract

See full text

An ultrasonic test device and test method for service stress of a moving mechanical component, where the device comprises an ultrasonic probe, a coupling fluid, a pressure-maintaining cover and universal wheels. The cover is vertically arranged above an inspected position of an inspected component, an interior of the pressure-maintaining cover is filled with coupling fluid, a bottom of the cover is provided with a structure permeable to the coupling fluid to form a coupling fluid film between the inspected position and the bottom of the cover, and a top of the cover is equipped with the ultrasonic probe. A detection part at a lower part of the ultrasonic probe extends into the coupling fluid of the cover and is vertical to the bottom of the cover without contact. The distance between the ultrasonic probe and the inspected component is kept unchanged through the universal wheels.
