In most applications, CSA delivers custom tuned devices, departing from the standard products in several ways:

• Smaller and larger units are available, with moving masses from grams to hundreds of kg.

• A wide range of resonant frequencies, from below 1 Hz to over 1000 Hz, is possible.

• Devices can be built in a variety of shapes and sizes, depending on the constraints of the application.

• Mechanical mounting can be tailored to an application.

The practical design challenge for TMDs is usually the part of the unit that dissipates mechanical energy into heat. CSA has designed TMDs with dashpots based on a number of technologies, including viscoelastic, magnetic, viscous and piezoelectric.

For even greater performance, or for applications requiring vibration reduction at multiple frequencies, an active vibration suppression system based on CSA’s SA series actuators may be appropriate.
