THE ALGORITHM STUDY OF THREE-DIMENSUIONAL ELASTO-PLASTIC CONTACT STRESS OF WHEEL/RAIL

  • The calculation of wheel/rail threedimensional elasto-plastic contact stress is the basisfor the research on wheel/rail contact fatigue. Thepaper first combines CONTACT program with finiteelement method, taking into account the real geometry and boundary conditions of rail, proposes aunited wheel/rail rolling contact numerical methodand computer software CMEF, which can calculatethe real elasto-plastic stress field of rail effectively.
