FEASIBILITY STUDY OF SHOCK ISOLATING A VERY LARGE STRUCTURE,
Abstract
This report considers the problem of suspending a very large structure within an underground cavity so as to provide adequate shock isolation. The geometry necessary to uncouple the modes of vibration of a simple system is studied, and recommendations are made concerning the relation between base and side springs. Coil-spring suspension systems are investigated and general design equations and charts are presented. Pneumatic suspension is considered. A new type of pneumatic suspension consisting of corrugated metal bellows is proposed and design equations and charts for such a system are presented. Liquid suspension is briefly discussed. Transient waves in various shock isolation systems are studied. The report concludes that pneumatic suspension systems employing corrugated metal bellows hold much promise and should be further investigated. Shock isolation of a very large structure appears to be feasible using either coil-spring or pneumatic-bellows supports. (Author)
