Structural Dynamic Properties of Tactical Missile Joints - Phase 1
Abstract
The report covers the first phase in a general study of the structural dynamic properties of tactical missile joints. The nature of the basic problem - sizeable and often unpredictable joint effects on airframe dynamic response - is traced in a brief aerospace industry and literature survey and explored in a parametric study designed to identify and illustrate controlling mechanisms and relationships. The importance of the number an spacing of load paths through a joint interface is developed in a conceptual analysis and clearly demonstrated in the results of a limited test program using simple idealized test specimens. Two analysis procedures for determining joint properties are briefly evaluated. The first involves a method for extracting multiple joint properties from missile dynamic test data. The second is based on direct application of finite element modeling of one of the test specimens. Both approaches show considerable promise and are concluded to merit further investigation.
