style="text-indent:25px">在鋼軌中軌頭工作邊上圓角附近的剝離主要是由以下三個原因引起的：由夾雜物或接觸剪應(yīng)力引起縱向疲勞裂紋而導(dǎo)致剝離；導(dǎo)向輪在曲線外軌引起剪應(yīng)力交變循環(huán)促使外軌軌頭疲勞，導(dǎo)致剝離；車輪及軌道維修不良加速剝離的發(fā)展。通常剝離會造成缺口區(qū)的應(yīng)力集中并影響行車的平順性，增大動力沖擊作用，又促使缺口區(qū)域裂紋的產(chǎn)生和發(fā)展。缺口區(qū)的存在，還會阻礙金屬塑性變形的發(fā)展，使鋼軌塑性指標(biāo)降低。軌頭核傷是較危險的一種傷損形式，會在列車作用下突然斷裂，嚴(yán)重影響行車安全。軌頭核傷產(chǎn)一的主要原因是軌頭內(nèi)部存在微小裂紋或缺陷（如非金屬夾雜物及白點(diǎn)等），在重復(fù)動荷載作用下，在鋼軌走行面以下的軌頭內(nèi)部出現(xiàn)極為復(fù)雜的應(yīng)力組合，導(dǎo)軌鋼公司，使細(xì)不裂紋先是成核，然后向軌頭四周發(fā)展，直到核傷周圍的鋼料不足以提供足夠的抵抗，鋼軌在毫元預(yù)兆的情況下猝然折斷，導(dǎo)軌鋼公司。鋼軌應(yīng)有足夠的高度，導(dǎo)軌鋼公司，其頭部和底部應(yīng)有足夠的面積和高度、腰部和底部不宜太薄。導(dǎo)軌鋼公司</p><div
