| 摘 要： | 提出了计算转子系统瞬态响应的精细迭代积分方法。采用精细积分法计算状态转移矩阵，可以得到齐次方程的精确解；结合轴承所提供的油膜力的特点，提出一种隐式积分法，允许使用较大的步长，并对各矩阵及向量适当分块，使非线形方程组的维数大为减小。此方法无条件稳定，可以保证较高的精度与效率。

| Abstract: | An iterative precise integration method is proposed to calculate the transient response of rotor-bearing systems.The state transfer matrices are calculated with the precise integration method and the precise solutions of homogeneous equations can be obtained.Therefore an implicit integration procedure is given in the light of the characteristics of oil film forces.The matrices and vectors are partitioned and the dimension of the nonlinear equations is reduced greatly.The integration method presented is unconditionally stable and can assure high precision and efficiency. |
