Abstract : High speed railway challenge the design, construction and maintaining of traditional railway, many traditional design
concepts have been changed. Transition of railway and bridge has two main problems. one is that different lines have
different ability of resisting distortion in area of trial load, which was known that problem of smooth transition of stiffness,
the other is that differential settlement between artificial structure and earth structure cause bending of railway. The
two problems have effect on train moving. The principle of processing transition of railway and bridge is same in world,
but it is difficult to find relationship between design standard of transition, vehicle performance, line standard, design
speed and so on form documentation and data reports. Based on mechanics, the paper analyzed dynamic performance of
transition of high speed railway, studied various rough elements which is effective to train moving, built mathematical
model of interaction of train and transition of high speed railway and developed numerical simulation software. In various
different work conditions, we did great quantity of numerical simulation, comprehensive analysis and performance
analysis.
