Abstract:
A control system for a failure mode testing system having a determinable system response, wherein the testing system includes 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, comprising: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; ande) storing the system response determination of the first pressure/frequency condition in a data storage medium.
