Non-contact method for evaluating bearing damage railway bridges

摘要

PROBLEM TO BE SOLVED: To provide a noncontact measurement method for a support part of a railroad bridge, which enables safe, efficient and quantitative measurement by performing inspection of the support part of the railroad bridge by using a noncontact sensor.;SOLUTION: In a noncontact measurement method for a support part of a railroad bridge, the vibration and displacement of the support part 2 of the railroad bridge are measured by a noncontact sensor 4 so that damage to the support part 2 of the railroad bridge can be quantitatively evaluated.;COPYRIGHT: (C)2014,JPO&INPIT
