Abstract
Abstract A shipboard transportation simulator moves a cargo container in an ocean wave-like simulation. A frame is supported for movement about a real axis, and supports the cargo container with its center of gravity above the axis. Counterweights suspend from the frame locate the combined center of gravity of the frame and container substantially at the axis. The frame and container are driven about the axis, whereby the container may be tested by reverse pendulum harmonic motion. A breakbulk table may be substituted for the container, to test breakbulk restraint systems.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
121 words
A shipboard transportation simulator for moving a cargo container in a wave-like simulation, said cargo container having a cargo center of gravity, said simulator comprising: a simulator frame; means for supporting said frame for movement about a real axis; means for driving said frame in movement about said axis; means on said frame for supporting said cargo container with said cargo center of gravity above said axis; said cargo and frame having a combined center of gravity; and means on said frame for balancing the moment about said axis of the cargo center of gravity for locating said combined center of gravity substantially at said axis; whereby said cargo container may be tested upon said simulator by reverse pendulum harmonic motion.
Claim 2
Dependent Claim
121 words
A shipboard transportation simulator for moving a cargo container in a wave-like simulation, said cargo container having a cargo center of gravity, said simulator comprising: a simulator frame; means for supporting said frame for movement about a real axis; means for driving said frame in movement about said axis; means on said frame for supporting said cargo container with said cargo center of gravity above said axis; said cargo and frame having a combined center of gravity; and means on said frame for balancing the moment about said axis of the cargo center of gravity for locating said combined center of gravity substantially at said axis; whereby said cargo container may be tested upon said simulator by reverse pendulum harmonic motion.
Claim 3
Dependent Claim
32 words
A shipboard transportation simulator as in claim 1 in which the frame supporting means includes an axle defining said axis and in which the frame is adapted for oscillation about the axle.
Claim 4
Dependent Claim
45 words

Claim 5
Dependent Claim
24 words
A shipboard transportation simulator as in claim 3 in which said operator positioning means adjusts the distance of said counterweight means below said axis.
Claim 6
Dependent Claim
20 words
A shipboard transportation simulator as in claim 1 in which the frame supporting means includes supporting bases for said frame.
Claim 7
Dependent Claim
