Patent ID: 7136769

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 a pressure and a 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 a function describing the system response; c) determining an energy level under a high pressure/high frequency condition and a low pressure/low frequency condition so as to define an energy level range; d) determining the slope of the function of the system response under a high pressure/high frequency condition and the low pressure/low frequency condition so as to define a slope range; e) determining whether the desired energy level falls within an energy level range; and f) determining whether the desired slope of the function describing the system response falls within the slope range.
