چکیده
In this paper, an Ultrasonic testing method for inservice wheel by use of phased array technology is introduced. To meet the ultrasonic test criterion of inservice CRH wheel, groups of phased array probes and conventional probes are combined used. By study echo wave in wheel rim and wheel disk form different probes, defect analyzing methods in wheel rim and wheel disk are studied. Tests on CRH reference wheels with manmade defects and on CRH wheels online shows that the arrangement of probes and defect analyzing methods can meet the requirement of field application.
