利用ABAQUS6.9有限元软件,以乳化液泵曲轴为研究对象,运用有限元分析软件研究曲轴的应力和变形情况,确定了曲轴的最危险相位和最大应力值。首先介绍了曲轴的网格处理方法,然后对曲轴的约束和加载作了必要的描述,最后按照乳化液泵曲轴的工作工况,进行了有限元分析,得到曲轴的应力分布云图和连杆轴颈圆角处的最小疲劳安全系数,为曲轴的设计和优化方向提供了充分的理论依据。 Using ABAQUS6.9 finite element software, the crankshaft of the emulsion pump was taken as the research object. The stress and deformation of the crankshaft were studied by finite element analysis software, and the most dangerous phase and the maximum stress of the crankshaft were determined. First of all, the grid processing method of crankshaft is introduced. Then the necessary constraints of crankshaft and the loading are described. Finally, the finite element analysis is carried out according to the operating conditions of the crankshaft of the emulsion pump. The minimum fatigue safety factor at the fillet of the neck provides sufficient theoretical basis for the design and optimization of the crankshaft.
