| 道岔軌下剛度不均勻?qū)嗆壪到y(tǒng)動力特性的影響分析(51 卷) |
| 英文標(biāo)題 |
| Analysis on influence of track stiffness irregularity beneath turnout on dynamic characteristics of wheel-rail system |
| 摘要 |
| 本文應(yīng)用剛?cè)岫囿w混合建模理論，建立道岔區(qū)車輛和鋼軌動態(tài)空間仿真模型，在模型中考慮了道岔區(qū)尖軌和心軌部位軌道的幾何不平順，考慮了由于道岔區(qū)鋼軌斷面分布不均勻、道岔結(jié)構(gòu)特征產(chǎn)生的結(jié)構(gòu)不均勻以及軌枕長度的變化、軌下基礎(chǔ)彈性分布等參數(shù)變化引起的軌道豎向剛度不均勻 |
