INVESTIGATION OF THE FEASIBILITY OF AN ELECTRIC NETWORK ANALOG FOR SOLUTION OF NUCLEAR GROUND MOTION PROBLEMS.
Abstract
The feasibility of an electric network analog containing only passive electric elements for use in the solution of nuclear ground motion problems was investigated. Postulating an axially symmetric elastic half-space to represent the ground, four basic forms of the electric analog were devised containing as electric elements inductance, capacitance, and ideal transformers. A small pilot model of the most attractive form of the analog was constructed and t sted and found to have unsatisfactory performance. The transformers used in the analog were specially built commercial units having a low leakage inductance. The poor operation of the analog was traced analytically and experimentally to excessively large voltage and current transformation errors in the transformers. The second problem encountered was the low cut-off frequency required (10 cps) of an analog containing a resonable number of mesh points. It was concluded that for the intended use the electric analog was not technically feasible at the present time. (Author)
