Abstract:

A test apparatus for testing the performance of a rotary drive includes a shalt which extends along longitudinal axis, at least one support for supporting the shaft in an elevated position and a flywheel of predetermined weight rotatably attached to the shaft so that upon rotation of the shaft the flywheel rotates as well. A rotary drive powers the rotation of the shaft and flywheel, the rotary drive having a hydraulic motor which is in fluid communication with a reservoir containing hydraulic fluid by way of a servo valve. A microprocessor controls the rotation of the shaft by the rotary drive. The test apparatus further includes a rotary encoder, a torque sensor, and pressure sensors for monitoring the angular displacement of the system, the torque on the shaft, and various system pressures respectively.
