| Abstract: |
| Based on the generalized probabilistic perturbation finite element method,the responses of vibration transfer path systems with uncertain paths is solved.The effective approach for response analysis of vibration transfer paths are presented using the Kronecker algebra,the matrix calculus,the generalized second moment method,the matrix perturbation theory,the probability and statistics.The random responses of multiple and/or multi-dimensional paths are described correctly and expressed in time range as uncertain factors are considered. |
