The subsystems are listed in Section \Ref{sec:PinnedBeam_sub}. This example represents the dynamics of a uniform beam with two pinned ends. The left-hand end is driven by a torque input and the corresponding collocated angular velocity is measured. The beam is approximated by 20 equal lumps using the Bernoulli-Euler approximation with damping. Because the two end lumps have different causality to the rest of the beam lumps, they are represented seperately. The system parameters are given in Section \Ref{sec:PinnedBeam_numpar.tex}. The system has 20 states (10 modes of vibration), 1 inputs and 1 outputs. The first 5 vibration frequencies are given in Table \ref{tab:freq} togtherr with the theoretical (based on the Bernoulli-Euler beam with the same values of $EI$ and $\rho A$. \begin{table}[htbp] \begin{center} \begin{tabular}{||l|l|l||} \hline \hline Mode & Frequency & Theoretical frequency\\ \hline 1 & 119.44 & 119.69\\ 2 & 474.83 & 479.02\\ 3 &1057.41 &1078.09\\ 4 &1852.85 &1914.86\\ 5 &2841.54 &2992.95\\ \hline \hline \end{tabular} \caption{Mode frequencies (rad $s^{-1}$)} \label{tab:freq} \end{center} \end{table} |
