[Balance] Types of Imbalance - Couple

 

Couple Imbalance

This illustration shows a TWA with two mass concentrations, equal and opposite in direction, and on opposite sides of the TWA centerline.
The centrifugal forces are shown as continuous waveforms.

Couple imbalance can be simulated as two equal weights placed on opposite planes in opposing directions.

As a vehicle travels at a high rate of speed, the passengers may experience a wobbling sensation which is typical of couple imbalance.
