曲轴弯曲疲劳试验对曲轴强度研究来说具有非常重要的作用,通过对球铁曲轴进行弯曲疲劳试验,用以验证4RC4 RC 4B5球铁曲轴在东方红自然吸气系列柴油机上不同存活率下的极限疲劳弯矩及安全性。通过相关试验和数据分析得出,球铁曲轴满足东方红自然吸气系列柴油机的需求。4RC 4B5
The crankshaft bending fatigue test plays a very important role in the study of crankshaft strength. The bending fatigue test of the ductile iron crankshaft is used to verify the limit of the 4RC4 RC 4B5 ductile iron crankshaft with different survival rates on the Dongfanghong naturally aspirated diesel engine Fatigue bending moment and safety. Through the relevant experiments and data analysis, the ductile iron crankshaft meets the demand of DFH naturally aspirated diesel engine. 4RC 4B5
