When a turnout is connected with CWR through welded joints, the longitudinal rail temperature force ACTS directly on the frog and the switch section along with the variation of rail temperature.
道岔与无缝线路焊接后，随着轨温的变化，长钢轨纵向温度力将直接作用于道岔的撤叉和转撤部分。
On the basis of finite element principle, a mechanical model is advanced for calculating the rail displacements and longitudinal forces of the welded turnout group. A computer program is designed.
基于有限单元法，建立了多组无缝道岔相联结时钢轨位移和纵向力的计算分析模型，编制了计算软件。
The guard rail plays an im po rtant role of ensuring the vehicle passing through the turnout zone successfully .
护轨对确保车辆顺利通过道岔起着重要的作用。
