| 標(biāo)題 |
| 鋼軌打磨對(duì)輪軌滾動(dòng)接觸斑行為影響研究(49 卷) |
| 英文標(biāo)題 |
| Study about influence of rail grinding on behaviour of wheel-rail contact spot |
| 摘要 |
| 高速鐵路鋼軌軌頭非對(duì)稱打磨有效地減緩了鋼軌疲勞斜裂紋的形成與發(fā)展。利用三維彈性體非Hertz滾動(dòng)接觸理論及數(shù)值程序CONTACT分析了鋼軌軌頭非對(duì)稱打磨對(duì)輪軌接觸斑行為的影響。結(jié)果表明，打磨后輪軌磨耗數(shù)有所增加，有利于預(yù)防鋼軌疲勞裂紋的形成。 |
