摘要
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。并以可动心轨提速道岔为例 ,分析了两组道岔的不同联结形式对钢轨位移和纵向力的影响。
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. As an example, the influences of the link style of two turnouts on the rail displacements and longitudinal forces of the Chinese No.12 turnout with moveable frog are analyzed.
