| Abstract: | In this paper,the shooting method combined with the principle of Floquet multiplier theory is ap-plied to study the effect of varying mesh stiffness and nonlinear journal bearing on the dynamic char-acteristics of unbalanced response and stability,The stability of equilibrium point is compared with thestability of periodic response caused by unbalanced mass. The difference of single shaft system and multi-shaft system is studied.The used method and culculated results may be useful for engineeringdesign. |
