摘要
由于铁路提速 ,柴油机中的一些大部件故障率升高 ,曲轴断裂问题尤为严重。本文就曲轴断裂的实质、影响疲劳的因素进行了分析 ,并相应提出了提高曲轴疲劳寿命的措施。
The failures of the larger parts of diesel engines are increasing with the railway speeding up.A serious problem is crankshaft break.The factors influencing the crankshaft fatigue life are analysed,and the countermeasures are also promoted at the same time.
