| 摘 要： | 分别采用简化法、协同法对某船用柴油机曲轴进行疲劳分析,根据FKM标准建立疲劳分析模型,在进行曲轴疲劳计算时,均考虑应力梯度、平均应力、加工工艺、可靠性等因素的影响。计算所得曲轴疲劳安全系数和应力幅值表明,简化法计算出的最小安全系数和应力幅值略大于协同法。

| Abstract: | The fatigue analysis methods for a marine diesel crankshaft were studied by respectively using the simplified method and collaborative method .According to FKM standard , the fatigue analysis models were established , during the crankshaft fatigue calculation, stress gradients, mean stress, processing technology, reliability, and other influence factors were considered in both simplified method and collaborative method .The safety factor and stress amplitudes were calculated .The results showed that the safety factor and stress amplitudes calculated by the simplified method is slightly greater than the collaborative method . |
