火车车轮踏面中电磁超声表面波声场性能测试方法的研究

THE RESEARCH OF THE MEASUREMENT OF EMA RALY WAVE ULTRASONIC FIELD' S DIRECTIVITY PATTERN ON THE WHEEL OF TRAIN

介绍了一种在火车车轮上电磁超声声场分布的测量方法,并给出了车轮上电磁超声表面波的声场 指向性的规律。

This thesis introduced a method of the measurement of EMA ultrasonic field' s distributing on the wheel of train, and it gave the law of EMA Raly wave sound field's directivity pattern on the wheel of train.
