Analysis of Torque Converter Dynamics

A good understanding of the torque converter dynamic behavior in a wide range of its operation gains the understanding of overall power train dynamic behavior, and facilitates design of different torque converter and power train control and estimation strategies. A detail analysis of the torque converter dynamics based on the linearized “static” and dynamic torque converter models is presented in the paper. The analysis results in simplified linearized torque converter models convenient for control and estimation purposes, and yields a clear insight to the torque converter capability of damping the power train vibrations.Copyright © 2002 by ASME
