Method for damping vibrations while testing a drivetrain having at least one shaft
First Claim
1. A method for damping vibrations while testing a drivetrain having at least one shaft,which shaft is connected to at least one drive or load machine for adjusting a drive or load torque,a reference value of the drive or load torque being specified for said machine,wherein a shaft torque is measured which is dependent on the relative twist between two points of said shaft,wherein the measured shaft torque is linked to the reference value of the drive or load torque via a delay line free from any differentiating member and added as such to the reference value of the drive or load torque to obtain an input value of the drive or load torque,wherein the at least one drive or load machine is operated at said input value.

Abstract
The invention relates to a method for damping vibrations while checking a drivetrain which has at least one shaft and to a device for carrying out the method. The shaft is connected to at least one drive or load machine for adjustment of a drive or load torque, a target value of the drive or load torque being specified for the machine. A shaft torque which is dependent on the relative rotation between two points on the shaft is measured, and the measured shaft torque as such is applied to the target value of the drive or load torque.
