Acceleration sensitive electric motion platform and a control system for controlling the same

摘要

A motion platform for supporting a g-force sensitive load, the motion platform includes base, a top having a g-force sensitive load bearing portion and a support portion. A support member supports the top relative to the base with freedom of movement about at least one horizontal axis and a pair of positioning motor assemblies mounted to the base. A respective arm assembly extends between each of the positioning motor assemblies and the top, and a microcontroller is electrically connected to the positioning motor assemblies for controlling a rotational speed and a rotational direction of said positioning motor assemblies and thus angular displacement of said top of the motion platform. The g-force sensitive load bearing portion of the top is displaced from the support portion of the top at which the support member supports the top. The arm assembly is responsive to rotary motion of a respective one of said positioning motor assemblies and adapted to rotate 360 degrees about the respective positioning motor assembly to effect relative movement of the top about the at least one axis.
