螺栓联接结合面接触分析及试验研究

根据结合面接触分形理论,论述了共形面接触刚度分形模型。对某低速重载设备的主动轴、法兰结合面接触受力情况进行了有限元仿真分析,发现螺栓孔缘处有应力集中现象。为了验证有限元仿真分析的可靠性,避免实际使用过程中孔缘处发生局部压溃现象,对主动轴、法兰联接组件做了等效件试验,试验结果与仿真分析一致,为低速重载机械同种结构的设计提供了可靠依据。...

Summary:根据结合面接触分形理论,论述了共形面接触刚度分形模型。对某低速重载设备的主动轴、法兰结合面接触受力情况进行了有限元仿真分析,发现螺栓孔缘处有应力集中现象。为了验证有限元仿真分析的可靠性,避免实际使用过程中孔缘处发生局部压溃现象,对主动轴、法兰联接组件做了等效件试验,试验结果与仿真分析一致,为低速重载机械同种结构的设计提供了可靠依据。

Based on contact fractal theory,a fractal model of contact stiffness was discussed.The stress concentration on the hole edges was found with a finite element analysis about stress distributing of the low-speed heavy-duty equipment shaft and flange.The experiments which can validate the reliability of the FEM simulation analysis and avoid collapsed phenomena on the hole edges were done.The results of the experiments are consistent with the FEM simulation analysis,and they provide reliable basis for the design of the low-speed heavy-duty equipment.
