METHOD AND APPARATUS FOR DAMPING VIBRATIONS IN A MOTION SIMULATION PLATFORM

摘要

A multiple degree-of-freedom motion simulator assembly comprises a fixed bas e, a displaceable simulator platform, and a plurality of linear actuators having upper ends thereof interconnected with the platform and lower ends thereof interconnect ed with the fixed base. A vibration damping unit is disposed between at least one of eac h of the upper ends and the platform and each of the lower ends and the fixed base. T he 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 actuato r. 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.
