Abstract Flow-induced vibration (FIV) at the spacer grid in fuel assembly of a Light Water Reactor (LWR) is leading cause failure. This project aims to produce simulation benchmark on experimental campaign MACE axial FIV cantilever beam an annular tube, that mimics configuration and environment typical LWR. The nuclear rod, which consists pellets filled Zirconium alloy cladding modelled experim...

Vibration of a floating roof in cases tube and foam seals has been analyzed by ANSYS. Fluid-Structure Interaction (FSI) sloshing phenomenon have considered. Modal responses, time waves frequency spectrums the vibrations two sealing were evaluated during horizontal seismic excitation tank base. Then, effects main mechanical factors seal on vibration investigated. The amplitude case was considera...

The longitudinal axial flow threshing cylinder of the full feeding rice combine harvester is widely used in China and works with violent vibration. To explore source excitation affecting vibration to reduce vibration, a finite element modal analysis multipoint input output (MIMO) test were performed solve natural characteristics. By analyzing frequency, we concluded that main reason for resonan...

A literature review on the subject of ambient vibration testing is presented, and a review of a recent study to illustrate state-of-the-art in the application of the ambient vibration method. Reports on testing of full-scale structures by the ambient vibration method began to appear regularly around 1970, with about 3/4 of all contributions devoted to the experiments in buildings, dams, chimney...
