Design and research on damage block of slot track for modern tram

摘要

In recent years, as a new form of public transport, the modern tram has been the rapidly developed and widely applicated at home and abroad. In order to ensure the safe operation of the modern tram, the groove rail damage block is used to explore suitable method of flaw detection. To solve the problem, finite element software was used to model the modern tramway structure, internal groove rail stress changes was analysised, the appropriate internal damage distribution was determined, combined with the corresponding national standard, a new groove rail damage test block was put forward, to determine the appropriate modern tram methods of flaw detection provide detection standard.
