Environmental Effects on the Center's Offset of the Kistler Force Plate

摘要

Kistler Force Plate (FP) (model 9286AA) with the corresponding software Bioware (2812A1-3, Version: 3.2.6.104) were used for the research described in the present paper. The software contains a number of equations for the calculation of all the variables obtained in the form of ampli fied electrical signals from the piezoelectric sensors incorpo rated in the FP. After a few measurements taken on the plate with the purpose of analyzing the influence of environment on the equilibrium of the human body we've obtained the set of values and graphs that the software offers. Knowing the equa tions, that the software uses to determine the forces and mo ments, we made a calculation using both the equations and the values obtained to get a closer look at the errors that can ap pear. As a result we observed a variance of the constant pa rameters representing the distance from the center of the plate to the center of each sensor. This article exposes the graphs obtained, the variance of the parameters that should normally be constant. The study was taken at Transilvania University of Brasov.
