Abstract
Abstract A motion generating system for simulator includes a multi-tier assembly of jacks. The multi-tier jacks permit a platform and equipment on the platform to move freely and safely in six degrees of freedom and to a maximum extent permitted by the mechanical properties of the jacks and joints. In the preferred embodiment of the present invention, a two-tier assembly of jacks connects the floor and the platform of a simulator for extending a maximum range in movement of platform and equipment on the platform.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
182 words
A system for generating motion for a simulator having a floor and a platform, said system comprising: a first tier of jacks; at least three mounting joints on said floor, each mounting joint coupling one end of two of said first tier of jacks; a second tier of jacks; at least three intermediate joints, each intermediate joint coupling the other end of two of said first tier of jacks and two of said second tier of jacks, each of said intermediate joints being coupled to at least two of said mounting joints by said first tier of jacks; a plurality of intermediate jacks, each of said intermediate joints being further interconnected with each other via one of said intermediate jacks; and at least three platform mounting joints on said platform for coupling to said intermediate joints by said second tier of jacks, each of said platform mounting joints being coupled to at least two intermediate joints by said second tier of jacks, such that the platform and equipment attached on an upper surface of said platform moves in six degrees of freedom.
