Abstract
This invention utilizes geometrically positioned strain gages attached to load cells (pylons) where each cell measures all force and moment components (Fx, Fy, Fz, Mx, My, Mz), thereby measuring all six degrees of freedom. The independent measurements eliminate the need for one cell's dependency on another, therefore reducing assumption, calculation, and cross-sensitivity errors. At least two load cells are attached to a top plate, to which the load is applied, and an optional bottom plate and an optional mounting plate. These force plates can be connected together to form an array of plates to measure multiple instances of load application over a greater area. The signals produced can be transmitted via wiring or wireless means either directly to a data collection device, or to a connector board, then through an optional pre-amplifier and a second stage amplifier for signal amplification and conditioning, then, finally, the data is received by a data collection device for interpretation and reading. The output can be six or more channels, and can be electronically combined to six channels.
