Polymax: a Revolution in Operational Modal Analysis
Recently the superior performance of the PolyMAX modal parameter estimation method using frequency response functions was demonstrated. The method can be implemented in a very similar way as the industry standard polyreference (time-domain) least-squares complex exponential method: in a first step a stabilisation diagram is constructed containing frequency, damping and participation information...
متن کاملDamping Estimation using Operational Modal Analysis
It has been observed that even though modal frequencies are well estimated using Operational Modal Analysis (OMA) techniques, damping estimation is not as accurate. The opinions on this aspect of OMA have been widely varying and no consensus or definite answers are available. In this paper the OMA procedure, data processing and modal parameter estimation, is studied with respect to proper dampi...
متن کاملFrequency Domain Techniques for Operational Modal Analysis
Operational Modal Analysis, also known as Output Only Modal Analysis, has in the recent years, been used for determination of modal parameters of civil engineering structures and is now becoming widely used also for mechanical structures. The advantage of the method is that no artificial excitation needs to be applied to the structure, or force signals to be measured. In this paper, the non-par...
متن کاملAn Overview of Operational Modal Analysis: Major Development and Issues
An overview of the major development of operational modal identification is presented. It includes four time domain approaches, i.e. NExT-type, ARMAV model-based, stochastic realization-based, stochastic subspace-based methods, and two frequency domain approaches, i.e. FDD-type and output-only LSCF-type methods. The internal relation with traditional modal identification using input/output meas...

syncope5 and suppuration in the groin after extra-vascular injection.6 The great danger, however, is that it is radioactive : ill results from this have been reported.9 Sodium iodide is likely to produce severe reactions and much pain, but it is still used for the aorta.10, 11 Organic iodides are the substances now usually employed. The most favoured is diodone (diodrast, Pyelosil). It is prepa...
