How it Works
As an example, a hoist system consisting of 12 parallel cables is to have the overall load distributed equally throughout the group within a specified percentage. To simultaneously determine the 12 individual forces, accelerometers are quickly mounted on each cable which are in turn “activated” by hitting them with a rubber mallet. The resulting accelerations are recorded with STS-LIVE and immediately uploaded into STS-CFA which calculates the individual forces and their deviation from the average. This information immediately indicates how much each cable must be adjusted to bring them into compliance.
