| 2 | Almost sure stability condition of weakly coupled linear nonautonomous random systems显示文摘In this study, the sufficient condition of almost sure stability of twodimensional oscillating systems under parametric excitations is investigated. The systems considered are assumed to be composed of two weakly coupled subsystems. The driving actions are considered to be stationary stochastic processes satisfying ergodic properties. The properties of quadratic forms are used in conjunction with the bounds for the eigenvalues to obtain, in a closed form, the sufficient condition for the almost sure stability of the systems. | T.W.MA | 2010 | Applied Mathematics and Mechanics(English Edition)2010，31，8： | 0 |
