輪軌蠕變力

1、輪和軌道的結(jié)構(gòu)彈性變形對(duì)滾動(dòng)接觸的輪/軌蠕變力的影響摘要本文簡要分析了機(jī)構(gòu)的結(jié)構(gòu)彈性變形對(duì)滾動(dòng)接觸時(shí)滾動(dòng)接觸性能的影響。詳細(xì)研究了輪和軌道結(jié)構(gòu)變形對(duì)輪軌滾動(dòng)接觸時(shí)的蠕變力的影響。對(duì)輪和軌道的一般性結(jié)構(gòu)彈性變形進(jìn)行了有限元分析，以及分別獲得了表示結(jié)構(gòu)彈性變形和相應(yīng)的滾動(dòng)方向負(fù)荷和橫向方向輪的關(guān)系。利用這些關(guān)系，我們計(jì)算了輪軌切線接觸的影響系數(shù)。這些影響系數(shù)說明結(jié)構(gòu)發(fā)生彈性變形與輪/軌接觸面上一個(gè)小矩形面積內(nèi)的單位密度牽引力有關(guān)。它們被用來修整一些由在 Kalker 以非赫茲形式的三維彈性體滾動(dòng)接觸理論中提出。
