| 1. | The fatigue alternating stress , which are highly variable in time , subject the crankshaft to very high and complex loading that induced to fatigue breakdown . the crankshaft design and manufacture must therefore precise calculations of the fatigue characteristics 柴油机球铁曲轴在工艺性和成本上占有一定的优势,通过滚压强化工艺,疲劳强度有很大程度的提高,因而在国外得到广泛应用。 |
