Abstract
A method is presented, together with variations thereof, which provides for identifying single degree of freedom machine operating characteristics from machine power transfer shaft torque and angular velocity measurements, wherein solutions are determined within the physical coordinate domain. Apparatus is disclosed which provides for variation in torque and angular velocity at the power transfer shaft and the shaft is accessible, so that independent measurements may be made. The determination of machine characteristics is useful for verification of analysis, diagnostics, or on-line monitoring for conformance to machine model characteristics.
