摘要
根据导出的修井曲线，进一步推导了在修井机绞车滚筒轴疲劳强度计算中的表达形式和应用方法。作为范例，结合８００ｋＮ级修井机的现场使用工况，完成了ＩＤＥＣＯ４６８５型修井机绞车滚筒轴的疲劳强度计算，取得了较为准确的结果。
Abstract According to the well reparing curve which had been achieved,a new form of expressing and applying method that used for the calculation of fatigue strength of well reparing rig drawworks shaft have been deduced.As an example,combining with the field materials of 800 kN well reparing rig,the fatigue strength calculation for the drawworks shaft of IDECO 4685 type well reparing rig has been completed,and the accurate result has been achieved.
