Patent ID: 7966890

Claim:
A high frequency multi-axis simulation system comprising: a test fixture having: a first linkage, the first linkage comprising first and second lever arms driven by a first actuator, the first linkage acting on a sample holder to bend the sample holder by moving first and second ends of the sample holder when driven by the first actuator, and; a second linkage, the second linkage comprising a bend tool driven by a second actuator, the second linkage acting on the sample holder to axially strain the sample holder and bend the sample holder by pressing on the sample when driven by the second actuator; a controller configured to operate the first and second actuators according to a user-specified first simulation profile and second simulation profile; a first artificial load driven by the first actuator; and a second artificial load driven by the second actuator; the first and second artificial loads increasing a resonant frequency of the simulation system; wherein the first and second artificial loads dominate a stiffness of the text fixture relative to a stiffness of the sample holder.
