| Influence of rail fastening spacing on dynamic gauge of ballastless track |
| 摘要 |
| 車輛的蛇形運(yùn)動(dòng)致使車輪輪緣與鋼軌內(nèi)側(cè)面相接觸，產(chǎn)生較大的橫向力，引起軌距的動(dòng)態(tài)擴(kuò)大?？奂亲柚逛撥壪鄬?duì)軌道縱橫向移動(dòng)的聯(lián)結(jié)零件，扣件間距是影響軌距動(dòng)態(tài)變化的重要因素。本文應(yīng)用有限元軟件Abaqus，建立車輛—軌道空間耦合動(dòng)力學(xué)模型，計(jì)算了列車運(yùn)行產(chǎn)生的動(dòng)力響應(yīng) |
