摘要
摇枕、侧架作为列车转向架的重要组成部分,对列车行驶安全起到至关重要的作用,各生产厂家亟须具有高穿透力的检测设备对其进行大批量的检测。本文介绍了应用于铁路机车关键部件无损检测的大型工业CT系统,论述了系统设计和扫描工作流程,并通过实例展示大型工业CT在摇枕、侧架等无损检测的应用情况。实际应用说明大型工业CT系统可对摇枕、侧架等关键部件的内部结构及内部的气孔、砂眼、夹杂物、缩孔、疏松、冷隔、裂纹等铸造缺陷进行快速有效检测,能够很好地满足该行业的需求。
Swing bolster and side flame, as important components of train bogies, play a crucial role in train movement. The requirements of high-penetration testing facilities for manufacturers to inspect a large number of workpieces are very strong. This paper introduced the large industrial CT system for the non-destructive inspection of the key components of the railway vehicles, elaborated the system design and the scanning flow, Through an example, we demonstrated the non-destructive testing application of industrial CT in imaging a swing bolster and a side frame. The successful practical applications show the industrial CT can be used in the detection of internal structure and defects of swing bolsters and side frames, such as internal air holes, sand and slag inclusions, porosity, shrinkage, cold shut and casting cracks and etc. The performance can meet the requirement of this industry well.
