Failure mode and effect analysis of knuckle pin for automatic coupling of state railway of thailand freight wagon
Abstract
Freight is major source of income of the State Railway of Thailand (SRT); which had
revenues of one billion baht a year. The development of freight by rail system to be fart,
punctual, and safe is important. Knuckle pin serves tension and shear stress in pulling
Rolling Stock. Strength testing of Knuckle pin must be done by technical and engineering
knowledge. SRT has 6,000 Rolling Stocks; that means, 6,000 Knuckle Pin has been used
and it is likely to increase due to the construction of the Double Track Project and the
purchase of new Rolling Stocks. The efficient Knuckle Pin prolongs lifespan and SRT would
have benefit on saving cost of maintenance and increase safety in the transportation of
goods. This research is aimed at creating the understanding about the quality of the
Knuckle Pin modeled Nat Mall. The pin would be test by Standard Test Methods for
Tension Testing of Metallic Materialsand the Standard Test Method for Analysis of Carbon
and Low-Alloy Steel by Spark Atomic Emission Spectrometry and Hardness Testing
Machine and Microstructureto determine the cause of pin’s damage. This study will
contribute the standardization of the quality of the Knuckle Pin which is used in Rolling
Stocks of SRT.
