Abstract
Abstract A motion simulator having mechanical actuators for moving a platform, or the like, in a controlled manner within specified limits and including fluid means arranged to exert a buoyant force opposing the gravity vector of the platform and equipment mounted thereon. In the disclosed embodiment, the buoyant means comprise a plurality of floats immersed in a liquid and connected to the motion platform by means of rigid links connected at opposite ends by means of suitable joints to the floats and platform.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
137 words
A motion simulator providing controlled motion to a body in space and comprising, in combination: a. a rigid frame supporting the body to be moved in a controlled manner; b. actuator means arranged to impart motion to said frame relative to a fixed base, said actuator means including a plurality of extensible actuators connected at opposite ends to said support frame and said base; c. control means for selectively controlling movement of said actuators; and d. buoyant means including a liquid medium and float means disposed and movable in said liquid and mechanically connected to said frame to exert thereon a biasing force opposing the gravitational force and representing a substantial fraction of said gravitational force, thereby substantially reducing the force required by said actuators to move said frame and body in opposition to said gravitational force.
Claim 2
Dependent Claim
137 words
A motion simulator providing controlled motion to a body in space and comprising, in combination: a. a rigid frame supporting the body to be moved in a controlled manner; b. actuator means arranged to impart motion to said frame relative to a fixed base, said actuator means including a plurality of extensible actuators connected at opposite ends to said support frame and said base; c. control means for selectively controlling movement of said actuators; and d. buoyant means including a liquid medium and float means disposed and movable in said liquid and mechanically connected to said frame to exert thereon a biasing force opposing the gravitational force and representing a substantial fraction of said gravitational force, thereby substantially reducing the force required by said actuators to move said frame and body in opposition to said gravitational force.
Claim 3
Dependent Claim
25 words
The invention according to claim 1 wherein said float means are constrained for movement in a substantially vertical path within container means for said liquid.
Claim 4
Dependent Claim
66 words
The invention according to claim 2 wherein a rigid link is connected at one end to said float means by a first joint and to said frame by a second joint, the total degrees of freedom of said first and second joints being at least equal to the degrees of freedom of movement of said frame relative to said fixEd base provided by said actuator means.
Claim 5
Dependent Claim
30 words
The invention according to claim 1 wherein said float means remain completely immersed in said liquid throughout all movement which may be imparted to said support means by said actuators.
