Dynamical analysis of transmission line cables. Part 2-damping estimation

In this work the authors try to establish a procedure to identify damping of transmission line cables in order to estimate in a simple (proportional) way the system damping matrix. The procedure is based on experimental and simulated data. The experimental data are collected through five accelerometers and the simulated data are obtained using the finite element method. To validate the mathematical model, the reduction of the system is used considering measured degrees-of-freedom. After that, the system damping matrix is estimated through different procedures.
