A cascaded overall actuating system for a vehicle motion simulator is
divided into an actuating system for small, high-frequency movements and
an actuating system for large, low-frequency movements. A manipulator for
implementing the low-frequency excitations is itself composed as a
cascaded system of a rotary plate, a six-axle movement unit and a
horizontal displacement device. To simulate movements which are as low in
frequency as possible, the horizontal displacement device spans, as the
actuator stage which is arranged at the lowest point in the cascade, a
large movement area of 40 m.times.40 m. The six-axle movement unit with
rotary plate and high-frequency actuating system is mounted on a carrier
carriage which is supported in a freely displaceable fashion on a planar
base surface bounded by the displacement paths of the horizontal
displacement device and is pulled and/or pushed with respect to this base
surface by means of the horizontal displacement device.
