Patent ID: 7024323

Claim:
A control system for a failure mode testing system having a determinable system response, wherein the testing system comprises: a plurality of actuator cylinders, each cylinder operating at an initial pressure and an initial frequency, wherein the frequency of each of the cylinders is different, the system configured to perform the steps of: a) selecting a desired energy level of the system response; b) selecting a desired slope of the fast Fourier transform of the system response; c) changing an operational parameter of the cylinders by a pre-selected amount in order to create a first pressure/frequency condition, wherein the operational parameter is selected from the group consisting of pressure, frequency, and combinations thereof; d) determining the system response in terms of energy and slope of the fast Fourier transform of the system response under the first pressure/frequency condition; and e) storing the system response determination of the first pressure/frequency condition in a data storage medium.
