Abstract EN
The paper deals with designing a control force to create nodal point(s) having zero displacements and/or zero slopes at selected locations in a harmonically excited vibrating structure.
It is shown that the steady-state vibrations at desired points can be eliminated using feedback control forces.
These control forces are constructed from displacement and/or velocity measurements using sensors located either at the control force position or at some other locations.
Dynamic Green’s function is exploited to derive a simple and exact closed from expression for the control force.
Under a certain condition, this control force can be generated using passive elements such as springs and dampers.
Numerical examples demonstrate the applicability of the method in various cases.
