Torsional vibration control for diesel-driven powertrains.
The need for reduced fuel consumption and the requirements mandated by vehicle spectator noise emission regulations have caused engine idle speeds to be lowered. Further, as strict diesel emission standards take effect and new engine models are designed with higher power-to-weight ratios, these diesels produce a harsher driving torque with a large vibratory component.
Such developments in diesel engines and drivetrains have changed the requirements for torsional vibration suppression and motion control, which has prompted the need for increased driveline ...
