Hybrid Knowledge Based System for Automatic Classificaton of B-scan Images from Ultrasonic Rail Inspection
Dutch Railways use a special train for the ultrasonic inspection of rails. The output of the ultrasonic scanning system installed on the train consists of echo images − so-called B-scans. The Bscans contain images of rail constructions, noise artifacts, and/or defects. Originally, all the images were interpreted and classified by an operator. Later, a simple rule-based classifier was build whic...
متن کاملطراحی و ساخت روبشگر فراصوتی جهت تهیه تصاویر روبش B (B-Scan) از قطعات صنعتی
The results of ultrasonic tests are usually displayed as A-scan signals. In an A-scan signal, reflections of ultrasonic wave form different reflectors are shown as sharp echoes on a time by amplitude display. Interpretation of these echoes can sometimes be quite difficult and usually requires knowledgeable and experienced specialists. There exist other methods of displaying the ultrasonic test...
متن کاملLong Range Inspection of Rail Using Guided Waves - Field Experience
Ultrasonic techniques have been used for many years for the inspection of rail. These measurements can detect the presence of a wide variety of defects but there are practical difficulties with the technology. While large transverse cracks of the type likely to cause catastrophic failure can be detected, the large, critical defects can be masked by large numbers of small, surface defects along ...
متن کاملAssessment of Ultrasonic NDT Methods for High Speed Rail Inspection
This article reviews some new ultrasonic rail inspection methods emerging in recent years. It focuses on the state of the art for guided wave technologies and their potential use for used for rail inspection. It considers ultrasound transduction options including EMATs, air coupled, pulsed laser and wheel probe guided wave methods. It compares performances in terms of frequency ranges, energy d...
متن کاملAutomatic Laser Ultrasonics for Rail Inspection
This paper presents the state of the current activities to develop a high-speed inspection system for evaluating rail defects. Since conventional contact ultrasonic techniques are speed limited, the aim was to build an automatic inspection system, which applies non-contact ultrasonic methods. An automatic Laser Ultrasonic system for Rail Inspection (LURI) has been developed and tested on a rail...
