| Research Abstract |
This study proposes to use Independent Component Analysis, ICA, toidentify vibration source of vehicles considering dynamical properties and examines the performance through numerical simulations and lab experiments. To find mixing matrix dynamically, integral, double integral, differential and double differential of accelerations measured on the body frame, which are treated as observed signals in ICA, are calculated. To examine the separation performance, two different types of vibrations are excited from the bottom of the experimental setup. Then, two different signals, which have similar frequency feature, are identified. Similar results are also obtained through numerical simulations. These results verified the proposed method.
