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.
- Auto excitation detection that identifies moment the cable begins to vibrate
- Auto peak finding algorithm that identifies cable’s the fundamental frequency of vibration
- Automatically selects the data range to be used for the FFT time-to-frequency transformation
- Easy-to-use graphical interface for verifying peak locations
- Cable properties input screen to allow for direct force calculation
- Output cable force data in spreadsheet format
- Use alongside other data acquisition systems
- Balancing cable forces for bridge and lift gate counterweights.
- Measuring cable support forces for bridges, radio towers, and industrial chimneys
- Estimated in-situ forces on bridge stay cables or vertical hanger cables
- Balancing hoist cable loads for river control structures
