Identification of excitation and reaction forces spectra for offshore platforms

Ahmed A. Elshafey, +8 more
- 19 Jan 2010 - 
TL;DR: In this paper, a simple method is used to predict damping and natural frequencies of a fixed offshore platform subjected to wind-generated random waves using its stationary response, and the method also predicts the...

ARX model for identification of bridge modal properties under live loading

Viet Hung Vu
TL;DR: In this paper, a multivariate discrete time invariant model is developed on the temporal response data of measured sensors to model the dynamic behaviour of the structure, and the model parameters are estimated and identified using a generalized least squares procedure.

Tilt errors of translational accelerometers attached to dynamic systems with tilt motion caused by the system response

Marius Tarpø, +3 more
- 28 Apr 2021 - 
TL;DR: In this article, the authors studied the tilt error of accelerometers attached to linear, stationary, and dynamic systems where the tilt motion originates from the system response and derived an impulse and frequency response function matrix for the measured acceleration from accelerometers.

Orthogonal functions techniques for the identification of mechanical systems

Ricardo P. Pacheco, +2 more
TL;DR: In this paper, a series of orthogonal functions are used for the identification of mechanical systems, where the input and output signals are represented by state-space equations, and the equations of motion can be integrated using numerical techniques together with integration properties specific for orthogonality.
