| 高速道岔尖軌矯直參數(shù)研究(51 卷) |
| 英文標(biāo)題 |
| Research on straightening parameters for turnout switch rail of high speed railway |
| 摘要 |
| 總結(jié)分析尖軌矯直前原始變形規(guī)律，并對(duì)變形進(jìn)行分類，研究了尖軌矯直支點(diǎn)壓點(diǎn)組合方法，采用彈塑性有限元方法建立了尖軌矯直三維實(shí)體模型，并計(jì)算尖軌矯直加載量。結(jié)果表明，尖軌矯直前初始變形分為單彎型、波浪型和空間曲線型三類，交替使用逐一矯直法和優(yōu)先矯直法，可提高 |
