CAE 300 Series Motion System
The CAE 300 Series Hydraulic Motion Base is a six degree-of-freedom Stewart platform. The six actuators have a stroke of 91.4cm, a bore of 8.9 cm and are equipped with hydrostatic bearings. Power for the system is provided by 3 37.3kW squirrel cage induction motors with matching variable displacement in-line pumps. The measured motion characteristics of the system are:
- bandwidth of 10Hz (3dB point)
- bandwidth of 5Hz (90° phase-nominal, can be extended)
- dynamic threshold < 67ms
- hysteresis < 1mm per actuator
