摘要
Abstract
Aiming at the defects such as blind detection and poor coupling effect of automatic detection of contact surface existing in the traditional ultrasonic detection technology used for detecting the de-fects of CRH wheel,a new parallel passive self coupling multi wafer probe mechanism is proposed, which can not only effectively eliminate the blind detection zone,but also ensure a good real-time cou-pling between ultrasonic probe and the wheel surface.A basic structure of the probe mechanism is in-troduced in this paper,and the degree of freedom of the mechanism is solved by using the topological structure theory based on the orientation feature set.An analysis is made on the mechanism for the au-tomatic detection of the kinematic performance,and by using relevant software,the mechanism pa-rameters are simulated,and the working space of the mechanism is obtained,which lays a theoretical foundation for the full implementation of the automatic ultrasonic detection of the train wheel defects.关键词
