| 客運(yùn)專線橋上無縫道岔模型之伸縮力試驗(yàn)與仿真分析研究(50 卷) |
| 英文標(biāo)題 |
| Retract force test of welded turnout model on passenger-dedicated railway bridge and its analytical simulation study |
| 摘要 |
| 在3×32 m無砟橋上以1∶3的比例鋪設(shè)一組客運(yùn)專線18號(hào)道岔模型進(jìn)行現(xiàn)場(chǎng)模擬試驗(yàn)，對(duì)橋上岔區(qū)內(nèi)的無縫道岔、無砟軌道、橋梁及相關(guān)傳力結(jié)構(gòu)的受力進(jìn)行模擬。采用非線性有限單元法建立橋上道岔區(qū)無砟軌道全橋一體化模型，算出相應(yīng)理論值，和試驗(yàn)值進(jìn)行比較，驗(yàn)證橋上岔區(qū)無砟軌道 |
