Paper Title:
Theoretical Analysis and Simulation Study on Track Rigidity of Turnout
  Abstract

Seriously inhomogeneous track rigidity of turnout will strengthen the dynamic response of wheel/rail system and shorten its service life. Combined with complicated structure characteristics of turnout, the simulation calculation model of track rigidity had been established. Main factors which influence the track rigidity were considered, such as the rail changing section, sharing baseplate, the foundation under rail. Distribution regularity of track rigidity in turnout had been obtained. The calculation result showed that track rigidity of turnout was seriously inhomogeneous. The maximum track rigidity was 162.2kN/mm in point rail of stock line, and the minimum track rigidity was 69.5kN/mm in stock rail of switch line.
