Abstract
A dynamic load test system simulates rotating mass torque loads encountered by specimen drive units such as complete motor vehicles, internal combustion engines, transmissions, brake systems and the like. The system includes a high pressure hydrostatic pump/motor unit which is controlled and regulated as a function of the positive or negative acceleration of the test specimen. Preferably, a portion of the total flywheel mass moment of inertia required for testing the specimen is generated by actual flywheel masses while a further portion is simulated by the hydrostatic pump/motor unit or a plurality of hydrostatic units.
