自己编的闻邦椿书上的Riccati法求临界转速。转子模型为单跨双圆盘模型，没有加入去除奇点的算法，结果可能有奇点，没有提取振型。-Own Wen Bangchun Riccati law book uates the critical speed. Rotor model for the single-span double-disc model, did not join the removal singularities algorithm, the results may have si

自己编的闻邦椿书上的Riccati求转子临界转速，转子为单跨双转盘。有去除奇点，提取振型，收敛迭代为弦截法。有各向异性求取临界转速部分，不过结果可能不准确。-Riccati Wen Bangchun own series of books on demand critical speed rotor, the rotor is a single span double turntable. There are singular point removal, extraction modes, t
