动静摩擦产生热弯曲易导致转子失稳。文中建立了发生摩擦热弯曲的转子 轴承系统的传递矩阵 ,利用传递矩阵对参数偏导数矩阵的递推公式得到了热稳定特征值对参数的灵敏度计算格式。
Dynamic friction generates heat bending easily lead to rotor instability. In this paper, the transfer matrix of the rotor bearing system with frictional thermal bending is established. The sensitivity calculation formula of the thermal stability characteristic value to the parameters is obtained by using the recursion formula of the transfer matrix to the partial derivative matrix of parameters.
