Abstract: A general modeling method is developed for the vibroacoustic analysis of an arbitrarily restrained rectangular plate backed by a cavity with general wall impedance. The present method provides a uniform way to obtain the ...

Abstract: A modified Fourier spectral element method (SEM) is developed to study vibration behaviors of general built-up systems that consist of various rotationally symmetric structures, including conical, cylindrical, and spherical ...

Abstract: Due to its long-span structure and large flexibility, an electrified railway catenary is very sensitive to environmental wind load, especially the time-varying stochastic wind, which may lead to a strong forced vibration ...

Abstract: ccording to the mean seasonal and annual precipitation from 30 meteorological stations in the periods of 1961?2008, the precipitation trends are analyzed by using the Mann?Kendall (MK) test in the Jinsha River basin (JRB). ...

Abstract: To investigate the thermoacoustic instability characteristics of a jet multinozzle array combustor, this study experimentally measured the flame describing function (FDF) of the model combustor using methane fuel experiments, ...

Abstract: Linear singlestage vibration isolation systems have a limitation on their performance, which can be overcome passively by using linear twostage isolations systems. It has been demonstrated by several researchers that linear ...

Abstract: A novel design of a two-stage nonlinear vibration isolation system, with each stage having a high-static-low-dynamic stiffness (HSLDS), is studied experimentally in this paper. The positive stiffness in each stage is ...

Abstract: This paper describes an experimental investigation into the vibration control of multiple electrical machines installed on a large-scale floating raft system. Vibration transmission to a flexible hull-like structure that ...
