摘要:
针对目前动车车轮缺陷所采用的传统超声波检测技术普遍存在检测盲区以及自动检测接触面耦合效果不佳等问题,提出了一种全新的并联被动式自耦合多晶片探头机构,不仅能有效消除检测盲区,而且能保证自动检测时超声波探头与动车车轮检测面的实时良好耦合; 根据实际检测时的探头的工作情况设计了探头机构的基本结构,并利用基于方位特征集的拓扑结构理论求解了机构的自由度; 分析了该机构用作自动检测时的运动学性能,并据此利用相关软件对机构参数进行数值模拟,得到了机构用作自动检测时的工作空间,为全面实施动车车轮缺陷的自动超声波检测奠定了理论基础。
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 defects 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 coupling between ultrasonic probe and the wheel surface. A basic structure of the probe mechanism is introduced 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 automatic detection of the kinematic performance, and by using relevant software, the mechanism parameters 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.
