Abstract EN
A number of Suspen-Dome structures have been built, but there is some difficulty in using experimental data to obtain good modal parameters, especially modal damping.
In this paper, an ANSYS numerical simulation of the 35.4 m span Suspen-Dome is presented.
Firstly, the natural vibration characteristics of Suspen-Dome and dynamic response under some random forces were obtained.
Then the results of the numerical simulation established that 60 modes are sufficient for a reasonable dynamic model.
This model is used to represent the Suspen-Dome dynamic behavior, and OKID is then used to try to identify a model from simulated data.
A 400-order model generated from OKID is shown to contain the 60 modes from ANSYS and is shown to give good predictions of the dynamic behavior of Suspen-Dome.
The results of this paper can confirm that it can be a very efficient tool for the identification of models of Suspen-Dome dynamics.
