| 重載鐵路12號固定轍叉道岔軌道剛度變化分布研究(52卷) |
| 英文標(biāo)題 |
| Theoretical study on track stiffness of No.12 fixed frog turnout for heavy haul railway |
| 摘要 |
| 本文通過建立重載12號固定轍叉道岔整體有限元分析模型，計(jì)算了岔區(qū)軌道剛度的分布特征。研究結(jié)果表明：道岔區(qū)軌道剛度不平順問題較為嚴(yán)重，基本軌剛度轉(zhuǎn)轍器區(qū)要大于連接部分和轍叉區(qū)，里軌剛度轍叉區(qū)最大，轉(zhuǎn)轍器次之，連接部分最小。 |
