| Abstract: | The numerical instability which usually exists in the conventional transfer matrix method can effectively be eliminated by using the Riccati transfer matrix method. The Riccati matrix method can facilitate the solution of the rotor dynamics problems especially for the high-speed, multiple supported, compound rotating systems. In this paper, following a brief introduction, the author applies the Riccati transfer matrix method to the critical speed analysis of the high-speed spindle on the spinning frame. With the help of a computer, the lowest three critical speeds are obtained and compared with the measured values and other method. The results show that they are in good agreement with each other. |
