摘要:钢筋笼分料盘自身惯量大、启动时间短,减速机末端的链轮轴受力复杂,在启动时会承受强大的冲击载荷。利用CATIA软件建立链轮轴的三维模型,并测量分料盘的转动惯量,将计算的动力矩作为瞬态动力学分析的载荷条件,联合ANSYS WorkBench对分料盘链轮轴在启动阶段承受载荷情况有限元分析,得到应力-应变曲线。结果表明链轮轴的强度符合设计要求。

Abstract:The lining plate of the reinforcing cage is characterized by large inertia and short starting time. The chain wheel shaft at the end of the reducer is complex in force and will bear a strong impact load at the start. This paper established 3D model of chain wheel shaft using CATIA software, measured the moment of inertia of the lining plate and regarded the dynamic torque calculation as the loading condition of transient dynamic analysis, then finite element analysis is carried out to obtain the stress-strain curve of the joint ANSYS WorkBench chain wheel in the starting stage. The results show that the strength of the sprocket shaft meets the design requirements.
Key words:chain wheel shaft;impact loading;ANSYS WorkBench;transient dynamics
