| 英文標(biāo)題 |
| Study on influence of rail bottom grade and profile of rail head on contact fatigue damage of rail |
| 摘要 |
| LM型貨車車輪分別與我國60 kg/m鋼軌和美國136RE牌號鋼軌匹配條件下， 60 kg/m鋼軌1∶40軌底坡時，輪軌接觸斑面積比1∶20軌底坡的面積小；美國136RE牌號鋼軌在1∶40軌底坡條件下的輪軌接觸斑面積與60 kg/m鋼軌在1∶20軌底坡時接觸斑面積相當(dāng)。鋪軌試驗(yàn)結(jié)果表明，60 kg/m鋼軌在 |
