摘要
叙述了用锤击法实测和分析汽轮发电机轴承控支承动刚度的原理和方法。介绍了一台３０ＯＭＷ汽轮发电机轴承座支承动刚度的实测结果和所进行的分析。用实测到的支承动刚度数据来计算汽轮发电机转子的临界转速，所得计算值与实测值很吻合。
This Paper describes the principle and method of measuring support dynamic stiffness of bearing pedestal of turbogenerator. As a example, support dynamic stiffnesses of bearing pedestal of a 300 MW turbogenerator were measured and analyzed .The criticals speeds of rotor were calculated with measuring actual data of support dynamic stiffness, its calculated values is identical with measuring critical speed values.
