OMNIDIRECTIONAL ELECTROMAGNETIC ACCELEROMETER,
Abstract
The report describes the design of an electromagnetic accelerometer suitable for measuring the drag accelerations in the falling sphere air density experiment. This instrument uses electromagnetic reluctance forces to restrain a steel, spherical mass. A mathematical model of the system is developed and used as an analysis tool. The system is highly nonlinear and a detailed examination of the nonlinearities is made. The design criteria developed from the mathematical model are applied to the construction of a single axis prototype. The experimental results indicate feasibility of the concept, but further studies are necessary to determine the ultimate limitations of the practical system. (Author)
