Abstract: Abstract. Blade tip timing (BTT) is a non-contact monitoring technology for rotor blade vibrations. Due to its severe undersampling, anti-aliasing spectral analysis has become a key focus. We identified certain specific ...

Abstract: In this paper, a multiscale approach has been developed for investigating the ratedependent viscoplastic behavior of polymer matrix composites (PMCs) with thermal residual stress effect. The finitevolume direct averaging ...

Abstract: Acting as an important internal excitation, sliding friction can cause the vibration and noise of the planetary gear set. In this paper, a dynamic model is developed to study the influence of sliding friction on the dynamic ...
