Single Mode |
Cheaper Controls and Actuators |
Equally Spaced Modes |
Simpler Controls and less Unstability |
Relatively Fixed Modes |
No need to track mode with expensive software |
Low Frequency Range |
Electronics are inexpensive if desired control
is below 500 Hz |
Heavy passive ( viscoelastic ) materials are
required for low frequency ( lower the frequency the higher the mass of
the damper ) |
Lightweight Structure to Control |
Can use piezoelectric stacks if high forces
are required |
|
You achieve best results if
all the conditions are met, then an active vibration control solution may be cost effevtive, even compared to a visoelastic treatment. |
