中文摘要：
振动和噪声通过多重和/或多维路径传递,振源、传递路径、受体及其动态交互作用的影响至今没有很好地解决,因此对于后续采用的被动控制或者结构修改以降低振动和噪声水平的技术来说,识别出主要的传递路径是至关重要的。本文基于一般概率摄动有限元法和结构可靠性理论,解决了时域内振动与噪声传递路径系统的路径传递概率的度量问题,提出了时域内振动与噪声传递路径系统的路径传递度的新概念和方法,在考虑工程中的不确定因素以后,在时域内清晰地描述了振动与噪声传递路径系统的路径传递率。
英文摘要：
Vibration and noise are transmitted through multiple and/or multi dimensional paths. The effects of transfer paths and dynamic interactions among them as well as sources and receivers are not well understood. Identification of dominant path（s） is crucial for subsequent passive control or structural modifications in order to attenuate vibration and noise levels. Based on the generalized probabilistic perturbation finite element method and the reliability theory, the path transfer probability of vibration and noise transfer path systems in time range is solved, and the new concept and effective approach of path losing probability for vibration and noise transfer path systems in time range are presented. The transfer ratios among multiple and/or multi-dimensional paths are described correctly and expressly in time range as the uncertain factors are considered.
