Abstract
Rail dip joint has been posing a problem with deterioration of track components and track irregularity due to the decrease of flexural rigidity and joint gap, Which has so far caused considerable maintenance cost. in this study static loading tests and wheelset drop tests have been carried out to clarify the difference between fish plate joint structure and standard track structure (no joint). Also, FEM model focusing on the decrease of flexural rigidity of fish plate joint structure was studied comparing with static loading test and wheelset drop test results.
