Effect of multiple weld repairs on fatigue strength of bogie frame of railroad vehicle

Autor: Jung-Won Seo, Hyun-Moo Hur, Seok-Jin Kwon, Kyung-Ho Moon

Publikováno v: Advances in Mechanical Engineering, Vol 15 (2023)

In the welded structure of railroad vehicles, the bogie frame requires a service life more than 25 years, cracks occur in the weld zone owing to the application of repetitive fatigue loading during operation. When cracks occur and propagate in the we
