連桿的主要損壞形式是疲勞斷裂和過(guò)量變形。通常疲勞斷裂的部位是在連桿上的三個(gè)高應(yīng)力區(qū)域。連桿的工作條件要求連桿具有較高的強(qiáng)度和抗疲勞性能；又要求具有足夠的鋼性和韌性。傳統(tǒng)連桿加工工藝中其材料一般采用45鋼、40Cr或40MnB等調(diào)質(zhì)鋼，硬度更高，因此，以德國(guó)汽車(chē)企業(yè)生產(chǎn)的新型連桿材料如C70S6高碳微合金非調(diào)質(zhì)鋼、SPLITASCO系列鍛鋼、FRACTIM鍛鋼和S53CV-FS鍛鋼等(以上均為德國(guó)din標(biāo)準(zhǔn))。合金鋼雖具有很**度，但對(duì)應(yīng)力集中很敏感。所以，在連桿外形、過(guò)度圓角等方面需嚴(yán)格要求，還應(yīng)注意表面加工質(zhì)量以提高疲勞強(qiáng)度，否則**度合金鋼的應(yīng)用并不能達(dá)到預(yù)期效果。
