<p>The dynamic properties of a machine (18) are defined by its kinetic energy, potential energy and dissipation functions. The machine is also identifiable by means of the nonviscous friction therein. These properties form the basis for the dynamic analysis of any machine. When the response (T,q) of a single degree of freedom machine (18) is observed while being driven by a forced periodic input torque (12) information is obtained whereby these functions together with the nonviscous friction characteristic may be determined. The apparatus and method by which such determinations may be made have applications in machinery development, quality control and diagnosis. </p> |
