| Abstract: | An experimental modal test of a bridge-type Cartesian robot subject to great centrifugal acceleration was presented. Based on the fundamental principle of modal analysis, the method of force-hammer excitation was adopted, applying exciting forces on multiple points and collecting the responding signals from a single point. The Varied-Time-Base analyzing method was used. After the modal analysis by DASP, three foremost modals were obtained. |
