Abstract
A method and an apparatus 10 for determining or identifying the torsional modes of a portion of a vehicle 12, such as a drivetrain assembly including a crankshaft 14, a driveshaft 16, a transmission assembly 18, and axles 24, 26. The torsional modes are discerned by use of the torque generator 14 such as an internal combustion engine, which is normally and operatively disposed within the vehicle 12, thereby obviating the need to replace the internal combustion engine 14 with a dynamometer and/or other type of signal generator assembly.
