seamless rail

基本解释

Aiming at vibration analysis of seamless turnout on bridge, the rail-turnout-tie-bridge spring-damping vibration model was built by using finite element method.
针对桥上无缝道岔，运用有限单元法，建立了钢轨-岔枕-桥梁弹簧-阻尼空间振动模型。
Cross sector seamless line, namely rail bar, rail bar and rail switch direct welding; the vertical force and displacement are direct transmitted between rail bars.
跨区间无缝线路，即轨条与轨条、轨条与道岔直接焊接，轨条之间直接传递纵向力和位移。
The rail temperature force and displacement inside seamless turnout decrease with the increase of pier stiffness.
岔区内钢轨的受力与位移随桥墩刚度增大而减小；
