摘　　要： 推导了带支反力矩的轴承数学模型和带支反力矩的计算转子临界转速的传递矩阵,并给出了计算实例和结果分析,得出了在支承刚度较大或轴承宽度较宽的情况下必须考虑支反力矩的重要结论。 The mathematics model of bearing countermoment and the transfer matrix of rotor system considering bearing countermoment in computing the critical rotational speed were deduced, and an instance and result analyses were given. An important conclusion was drawn that it is absolutely necessarily to consider the bearing countermoment in case of large supporting rigidity and wide bearing width.

关 键 词： 轴承 力矩 传递矩阵 转子
