Torque Converter as a Vibration Damper and Its Transient Characteristics

Equations of nonsteady-state motion of a torque converter were established and its speed changing performance was obtained. Damping effects of a torque converter on torsional vibrations were clarified by linearizing the equations around a steady-state operating point. Theoretical results showed good agreements with experiments. It was found that steady-state characteristics may be used in the analysis of a nonsteady-state phenomenon.

Torque converters were successfully simulated by a vibration model, which simplified the vibration analysis of a system.
