ESS RFQ Experimental Modal Analysis

2022
The European Spallation Source-ESS, which is currently under construction and commissioning at Lund, Sweden is a neutron source that consists of a 2 GeV linear accelerator (LINAC) accelerating a proton beam to a solid Tungsten (W) target. The proton beam is produced by the Ion Source (ISRC) and transported through the Low Energy Beam Transport (LEBT ...

Trends in experimental modal analysis

Mechanical Systems and Signal Processing, 1987
Abstract The scope of this paper is to comment on current trends and new developments in the field of experimental modal analysis. The first section covers modal measurement and estimation procedures, with special emphasis on the use and limitations of recent techniques such as multiple input processing, total least square, global time- and frequency

Nonlinearity in experimental modal analysis

Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2001
Summary: Modal analysis is established as one of the fundamental strategies in approaching structural dynamic problems. Despite its universal appeal, it is fundamentally a linear theory and cannot be applied to significantly nonlinear systems without incurring substantial difficulties in implementation and interpretation of results.

Elements of Experimental Modal Analysis

2008
Fundamental concepts for the characterization of the dynamical response of SDOF and NDOF systems are provided. A description is given of the main techniques to represent the response in the frequency domain and its experimental characterization.

A Separation Modal Method of Experimental Modal Analysis

The Shock and Vibration Digest, 1991
The test is carried out in a laboratory and the testing sample, which is a cylindrical thin-shell made of a composite, is in a free-free state.
