6 Degrees of Freedom Motion Platform
moving platform (mpg - 509 kb)

One of CAREN’s main components is a 6 degrees of freedom motion platform. Manufactured by Rexroth-Hydraudyne (NL) and customized to meet MOTEK’s specifications for quick response times on one hand and no faults or complicated maintenance, on the other. The platform is capable of carrying up to 3 people and of giving very quick response for long periods of time (up to 500Hz). The system is a hybrid of Electric and Hydraulic actuators, giving quick and short responses when using the electric actuators and slower but longer responses, when the hydraulic actuators are used. The motion platform is simple to operate and it uses a standard P. C. for the basic controls and maintenance.

Motion Platform Technical Specs

The Motion Platform is combined out of four main components:
  • Motion Computer - MC
  • Motion Control Cabinet - MCC
  • Motion Base – MB
  • Hydraulic Power Unit - HPU

The Hydraulic Power Unit gets power from the Power Unit Control Cabinet (PUCC), which take 440 VAC 60 Hz, 3 phases for US and Canada and 400VAC 50Hz 3 phase power for other countries, and is located just alongside of the Hydraulic Power Unit. The Motion Computer and Motion Control Cabinet get standard 110V 60Hz for US and Canada, and 230V 50 Hz in other countries.
