摘　　要：为了寻求偏心度与偏心特征量之间的数值关系,采用解析计算与有限元相结合的方法计算偏心特征量数值,建立偏心状态下复杂气隙模型,并采用动态卡式系数理论分析开槽对气隙的影响,分别推导静偏心及动偏心状态下的气隙分布函数,求出偏心特征量的解析式。并且应用有限元计算的方法验证理论分析的有效性,该方法为偏心检测奠定了理论基础。In order to find the numerical relationship between eccentricity degree and eccentric characteristic parameters, the analytical method and element finite element method were used to calculate the eccentric characteristic parameters. A complex air gap model was established to de scribe the air gap length under eccentricity. The dynamic cater factor theory was proposed to analysis the slotting effect on the air gap, and the characteristic parameters with static and dy namic eccentricity were thus obtained. The of the proposed calculation. This paper lays element finite method was used to verify the validity a solid foundation of the detection technology of rotor
