The rail fastening system plays a crucial role in railway tracks as it ensures operational safety by fixing the on to sleeper. Early detection of fastener defects is ensure track and enable maintenance optimization. Fastener inspections are normally conducted either manually trained personnel or using automated 2-D visual inspection methods. Such methods have drawbacks when visibility limited, ...

The study proposes processing animation simulation, FEM analysis, and experimental verification of multi-stage forging of stainless automotive battery fastener. The processing animation simulation can provide the realistic motions for each pass to realize how to work for the front punch and die. Stainless automotive battery fastener requires high dimension precision and narrow tolerance. In ord...

Especially for ageing aircraft the development of fatigue cracks at fastener holes due to stress concentration and varying loading conditions constitutes a significant maintenance problem. High frequency guided waves offer a potential compromise between the capabilities of local bulk ultrasonic measurements with proven defect detection sensitivity and the large area coverage of lower frequency ...

Abstract This article projects the systematic approach for reducing rejection during manufacturing of non-threaded fasteners i.e., Dowel Pin by Basic Quality tools. It includes study process fastener and its inspection at different stages manufacturing. The analysis Pin’s has been taken place industry A modification in process, drawing work holding device Machine Tool have done. After implement...
