Modelling, analysis and testing of dissipative beam joints -experiments and data smoothing

The modelling, analysis and design of beam joints are important in the study of control and stabilization of modern large flexible space structures. In this paper we first briefly summarize our recent findings in the modelling of dissipative beam joints and their vibration eigenfrequency analysis. We then present beam joint experiments and the recorded data. We process the data by least square smoothing. The smoothed data shows strong consistency with the theoretical estimates. This in turn supports the correctness of our modelling as well as the accuracy of experimental measurements.
