平稳随机过程激励下模糊随机梁的动力响应分析
Dynamic analysis of fuzzy-random beam under stationary stochastic excitation
摘要
Abstract
The fuzzy-random correlation function matrix of structural displacement response in time domain as well as the fuzzy-random mean square values of structural dynamic response in frequency domain are derived in this paper with the structural physical parameters and geometric dimensions for the beam are fuzzy-random.So the fuzzy numerical characteristics of dynamic responses are then addressed based on the theory.The validity of the method presented is verified and illustrated via an engineering example,and results display that the uncertainty of structural parameters should not be neglected during the analysis of the structural dynamic response.关键词
