This paper clarifies the nonlinear and non-stationary characteristics of transient vibration of a single-disk rotor system on anisotropic supports passing through critical point under limited energy supply by analytical dynamics and Bogoliubov-Mitropolskii asymptotic method. The governing equations for the motion of the system are finally reduced to a first order differential equation system capable of numerical integral solution. The influences of gyroscopic effect of the rotor, external and internal damping as well as the initial phase angle of static unbalance on the transient response are discussed.

Discussed in this paper is a class of nonlinear parabolic differential equations with forced oscillation in various boundary conditions. Green's formula is used to study the forced and nonhomogeneous term of boundary conditions. Necessary conditions are thus obtained for the existence of nonoscillatory and positive solutions for a first order differential inequality. Sufficient conditions are also established for solutions with oscillations.
