The in-depth analyses and simulation calculations of two simplification methods are carried out in this paper. Then it is pointed out that the equivalent d- and q-axes damper winding model is not suitable for calculating the internal short circuits because the concept is not applicable in this situation, and the errors caused by it are too obvious to be accepted in electrical engineering; while the approximate damper cage model is acceptable since it not only meets the accuracy requirement of electrical engineering but also saves calculating time for computers.

本文对阻尼回路的2种简化方法进行了深入分析和仿真计算，指出等效d轴和q轴阻尼绕组模型应用于电机内部短路计算时，物理概念上存在缺陷，且会造成过大的误差、在工程上无法容许；而近似阻尼笼的处理方法既能满足工程精度要求，又可节省计算时间。

The results show that the vibration intensity of the substructure has a connection with the depth of the well, the geological condition and the density of drilling fluid; the horizontal vibration of the substructure is mainly caused by bent kelly; the included angle between the axis of cardan shaft and the derrick floor is also the cause of the vibration in three directions, and the cause of t...

分析结果表明，底座的振动强度与井深、地质条件和钻井液密度有关；弯曲的方钻杆是造成底座水平方向振动的最主要原因；万向轴因与钻台面存在夹角，从而引起底座在三个方向的振动；采用四挡钻进时，万向轴的工频及其倍频接近底座垂直方向的固有频率是引起底座在该方向振动强烈的原因。
