Research on widening construction clearance on the transition curve of existing railway lines based on SIMPACK

  This paper selects appropriate vehicle as the standard vehicle and designs its shape.Secondly,it chooses some control point on the vehicle according to the current standard.Thirdly,the essay sets four difficult operating conditions with different curve radius and superelevation,simulates on the SIMPACK software and compares the value of control points offset the centre of railway line to the current construction clearance.According to the result of comparison,this paper divides transition curve into three parts to widen construction clearance and proposes the definition of correction coefficient.At last,the paper compares construction clearance that has been corrected with existing construction clearance to check whether the new one is right or not.The study shows that if curve part is divided into three parts to widen construction clearance,it would be more reasonable and satisfactory.
