Parallel Piezoelectric Shunt Damping of Rotationally Periodic Structures

Figure 7

Disk experiment: comparison between the independent shunt and parallel shunt for the first mode with nodal diameters. The dotted lines correspond to the original system, with a natural damping of 0.5%. (a) is measured at the point where the sine mode is maximized. (b) is measured at the point where the cosine mode is maximized. (c) is measured in the midway, where both modes contribute to the response.
