摘要: 在转子动力学的基础上,采用连续分布式阶梯梁模型的思想建立了钻井泵曲轴的动力学分析模型,研究了钻井泵曲轴动不平衡量与振动量之间的关系,并推导出了它们之间的关系方程。结果表明,只要测得轴承处的晃动值就可以确定钻井泵曲轴的总动不平衡量,为曲轴的动平衡设置平衡重提供了理论依据,进而控制钻井泵的振动。

Abstract: Based on the rotor dynamics theory,the dynamic model of crankshaft is build based on the continuous distributional ladder beam model to study the relationship between dynamic unbalance and vibration of crankshaft in drilling pump,and their relational expression is derived.The result shows that the total unbalance of crankshaft can be determined as long as the vibration amplitudes of bearing are measured.And it provides theoretical basis for setting up balance weight at crankshaft to control the vibration of drilling pump.
