随机振动在时域分析中的某些问题
|
摘要
本文用状态空间方法给出随机振动在时域分析中的一些研究成果。 振动的主动控制,本文对主动减振的状态及其应用前景作了综述并介绍了线性控制系统的设计方法及减振后的响应分析方法。 非零均值随机作用下振动系统的响应分析。本文提出一种在非零均值非平稳高斯激励下获得等效线性系数的封闭公式及多自由度系统响应的分析方法。 带时滞随机外作用下振动的响应分析,本文提出的方法对平稳及非平稳情况都能适用语当用等效线性化的方法,此法还可推广应用于非线性系统。
This paper presents some results in random vibration analysis by state space method in time domian.Vibration absorption with active control. An overview of vibration absorption with active control and its future application are discussed, as well the design method of linear control system and its response results.The response analysis of vibration systems due to none zero mean random excitation. An equivalent linearization method for obtaining the closed formula of the coefficients of the linear system and the method of response analysis of nonlinear multidegree dynanic system to nonstationary Gaussian excitation with nonzero mean are introdused.The response analysis of vibration system to stochastic excitation with time lag. The method presented is suitable for random excitation in both stationary and nonstationary cases, and its application may be extended to nonlinear analysis if equivalent linearization technique is used.
