摘要：
Transient energy response analysis of vibro-acoustic systems with fuzzy uncertainty is investigated by researchers. The first test model is a plate–cavity system consisting of a simply supported plate and a cavity with rigid walls. The analysis frequency band is set to [1778, 2239] Hz. The fuzzy uncertainties in statistical energy analysis (SEA) parameters are considered. The SEA parameters of systems are regarded as fuzzy parameters with triangular membership functions. The membership function of each fuzzy parameter is divided into four sublevels. The Monte Carlo method (MCM) with 106 samples is used to validate the accuracy of reduced transformation method (RTM).
