铁路道岔滑床板断裂分析
Fracture Analysis of Slide Chair of Railway Turnouts
摘要
Abstract
By means of chemical composition analysis, metallographic examination, fracture analysis and so on, the fracture reason of turnout slide chair was analyzed. The results showed that the main failure reason was the too large cyclic tensile stress caused by the structure and installation of the slide chair, and the weld quality control should be noted.关键词
