Damper Kit for TM165
Model Number: TM165A
An optional eddy current damper kit for investigating viscous damping in rotor oscillations.
Overview
A simple eddy current damper for use with the TM165 Free Torsional Vibrations. Students may fit an optional Damper Kit (TM165a) to test how viscous damping affects the rotor oscillations. This kit includes a bracket that holds a powerful magnet above the rotor of the TM165. The magnet induces eddy currents in the oscillating rotor, opposing and damping its motion. The damping effect is proportional to velocity and becomes zero when the rotor stops oscillating. This makes it a form of viscous damping. When using the Damper Kit, VDAS® can fit its displayed data to underdamped viscous damping models.
