摘要：

Previous work on in-situ calibration of force platforms has focused primarily on behaviour under static loading conditions. The prototype described in this paper is a dynamic system, designed to approximate the loading profile generated during human gait. The design, construction and performance of an oscillating lead pendulum assembly is described; including three-dimensional visual performance assessment and rigorous multi-component force analysis. No significant difference was found between measured data and a theoretical profile for vertical force and angular displacement. A significant difference was found for the horizontal force component. The authors believe that further development of this prototype model will allow accurate routine dynamic calibration. (C) 2000 Elsevier Science B.V. All rights reserved.
