| 標(biāo)題 |
| 高速列車通過半徑2 200 m曲線動力學(xué)性能的試驗研究(49 卷) |
| 英文標(biāo)題 |
| Experimental study on dynamic performance of high-speed train passing curved section with 2 200 m radius |
| 摘要 |
| 鐵路既有線小半徑曲線的允許速度問題直接關(guān)系到我國既有線提速目標(biāo)的完成，以最小曲線半徑2 200 m為例，進(jìn)行曲線動態(tài)測試，并從舒適度角度考慮列車運行的安全性和舒適性。結(jié)果表明，半徑2 200 m曲線宜提速到180 km/h。 |
