A new of motion simulator has been developed that consist from suspended cabin that is maneuvered by robotically-controlled steel cables. It could be installed in rooms and can be moved greater distances and at greater speeds than standard simulators.
The simulator has been developed by the Fraunhofer IPA in collaboration with the Max Planck Institute. It is based upon cable-driven technology that can be used for moving around large objects in large spaces. The cabin is made from carbon fiber tubes and is designed to withstand the high forces when it is pulled by the cables. It is enough space inside to install projection surfaces like cockpit.
The cabin is suspended by eight cables that are each tensioned at up to 1.4 tons and are attached to winches that control the direction and speed of the cabin as they coil. That way cabin moves freely throughout the space.
Weight of the cabin frame is 80 kg and sizes a space of diameter 5 m x 8 m x 5 m. The total winch drive power is 348 kW, that allows for acceleration of up to 420 m/s2 (meters per second squared). This acceleration is far greater than is possible with conventional, actuator-mounted simulators. Movement sensations can be simulated with forces acting upon the cabin up to 1.5 g. This technology could be used for driving or flight simulation, but also to explore perception processes in humans. The video below shows the simulator in action.
