Electromechanical actuator test apparatus

An electromechanical actuator test system, comprising:

• an inertia simulator adapted to be coupled to a plurality of test actuators and configured to simulate the inertia of at least a portion of a system moved by the test actuators;
• a first axis first load actuator coupled to the inertia simulator, the first axis first load actuator coupled to receive first axis first actuator commands and operable, in response thereto, to supply a first load to the inertia simulator along a first axis;
• a first axis second load actuator coupled to the inertia simulator, the first axis second load actuator coupled to receive first axis second actuator commands and operable, in response thereto, to supply a second load to the inertia simulator along the first axis;
• a second axis first load actuator coupled to the inertia simulator, the second axis first load actuator coupled to receive second axis first actuator commands and operable, in response thereto, to supply a third load to the inertia simulator along a second axis, the second axis perpendicular to the first axis;
• a second axis second load actuator coupled to the inertia simulator, the second axis second load actuator coupled to receive second axis second actuator commands and operable, in response thereto, to supply a fourth load to the inertia simulator along the second axis;
• and
• a test system control operable to supply the first axis first and second actuator commands and the second axis first and second actuator commands.
