The camshaft is one of the most important rotating parts in diesel engine. As a continuous rotating part, the high-cycle fatigue problem of camshafts has always been a hotspot in engineering. Generally speaking, nominal stress method is used to analyse high-cycle fatigue problems, but the continuous operation of camshafts determines that nominal stress method can not be used directly. Based on this, a load-discretization method based on the fatigue cumulative damage criterion and nominal stress method is proposed to solve the fatigue calculation problem of continuous rotating parts.
