通过建立大型回转轴承装置的振动模型，以大量的试验数据为依据，提出了一套从试验条件与参数的选取到最后分析结论判定的系统方法。

Based on the vibration model and testing data, the paper provides a systematic way to not only the choice of testing parameter but also drawing the conclusion.

对测量仪进行精度校核是保证测量精度的前提，精度校核分为测头校核与回转轴校核，通过测头校核可修正测头、测杆以及复位参数。

Precision checking is the precondition of the machine precision. It includes probe checking and rotor checking. Probe and reposition data can be modified through checking.
