Giant Magnetostrictive Transducer and Its Application in Bridge
To the scene quickly and accurately read the travel time of each ray ti, enter the location of each ray coordinates of the emission source and receiver coordinates of the transducer, the computer can immediately calculate the velocity profile Vl), and use high Figure that out of ridicule, the results shown in Figure 5. l ■ - ridicule Ju Bin Bin tunnel a JI!

Zhu: Zhu: Zhu: Zhu: Zhu: Zhu: Zhu: Zhu l Figure 5 detection section CT imaging results Fig5ThewaveCTresult seen from Figure 5, in which the bridge has a large area below the speed of sound 4000m / s, which shows that the poorer dense concrete bridge, the corresponding strength of the bridge is not high,[link widoczny dla zalogowanych], which is the section of the bridge is scrapped the bridge. The examples above simply super-rare earth magnetic transducer works in the acoustic detection of CT in the actual testing required under the relevant testing standards for testing, such as \5 Conclusion This paper introduces the relevant rare earth giant magnetostrictive material properties, quality inspection of major projects for the current nondestructive evaluation system for acoustic source of the new requirements, the development of rare earth magnetostrictive transducer, the transducer with high power rare-earth magnetostrictive material as the source, with a focus on energy and emission wave propagation distance, frequency for data reproducibility and ease of use and safety. Taking a bridge acoustic CT nondestructive evaluation of its wide application as an example. References: [1】 WAVE. [J】. Progress in Geophysics, 2003,18 (3) :368-369. [2】 WAVE. [J】.
