Design of ultrasonic automatic testing system for locomotive wheels
摘要
Abstract
Aiming at the situation that the defects of the locomotive wheels are complex and hard to test,and manual way of ultrasonic testing is unreliable,an ultrasonic automatic testing system for locomotive wheels was proposed.The system was designed from mechanical module,ultrasonic detection process,motion control and software module.With the help of 2 groups of probes at the tread and inner side surface,the comprehensive tes-ting for the wheel defects can be conducted,and there are total 14 probes for a wheel set.The probes and part of wheel are immersed in water to collect ultrasonic signal.And the wheel keeps rotating and the probes are rela-tively fixed when the test is started,so the system can detect wheel’s defects quickly and efficiently.Compared with manual testing,the system can significantly improve the efficiency and reliability of the wheel testing.关键词
