Structural Dynamic Properties of Tactical Missile Joints -Phase 3.

摘要

The results of a third and final phase in a general study of the structural dynamic properties of tactical missile airframe joints are presented. The overall objectives of the study were to provide a better understanding of mechanical joint effects on missile dynamic response to improve methods for predicting and representing their characteristics in system simulation and response studies. Finite element structural analysis techniques started in Phase 1are shown to be capable of providing reliable estimates of joint compliance in complex actual missile structures. A technique for extracting joint compliance values from missile model test data started in Phase 1is refined to improve convergence and user convenience. A user's manual for the joint compliance extraction digital computer code is included as an appendix to the report. (Modified author abstract)
