Abstract
A multiple degree-of-freedom motion simulator assembly comprises a fixed base, a displaceable simulator platform, and a plurality of linear actuators having upper ends thereof interconnected with the platform and lower ends thereof interconnected with the fixed base. A vibration damping unit is disposed between at least one of each of the upper ends and the platform and each of the lower ends and the fixed base. The damping units include at least a first resilient member preloaded and mounted to a major surface of a plate of the damping unit engaged to one of the ends of the linear actuator. The first resilient member provides vibration absorption such as to damp vibrations transmitted from the plate to the platform or base in at least a direction substantially perpendicular to the major surface.
