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。各生产厂家亟需具有高穿透力的检测设备对其进行大批量的检测。本文介绍了采用工业CT技术的一种新型的CT/DR扫描系统,能够对摇枕、侧架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无损检测,能够很好地满足该行业的需求。
Swing bolster and side frame, as important components of Train bogie, play a crucial role in train movement. The requirements of high- penetrated testing facilites for manufactures to inspect a large number of workpiece are very strong. This essay introduce a new CT/DR scanning system which adopt industrial computed tomography and can be used in the situation of nondestructive detection to internal structure and internal blowhole,sand hole,slag inclusion, porosity, shrink, cold shut and casting crack etc of swing bolster and side frame, It can meet the requirement of this industry well.
