seamless rail

基本解釋

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.
針對橋上無縫道岔，運用有限單元法，建立了鋼軌-岔枕-橋梁彈簧-阻尼空間振動模型。
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.
跨區(qū)間無縫線路，即軌條與軌條、軌條與道岔直接銲接，軌條之間直接傳遞縱曏力和位移。
The rail temperature force and displacement inside seamless turnout decrease with the increase of pier stiffness.
岔區(qū)內(nèi)鋼軌的受力與位移隨橋墩剛度增大而減?。?/li>
