Structural Dynamics Modeling and Testing of an Air-to-Ground Missile System

摘要

The Platform Integration Function, Aviation and Missile Research, Development, and Engineering Center located at Redstone Arsenal, Alabama developed structural dynamics models and performed experimental modal testing on an Air-To-Ground Missile System. The purpose of this project was to understand the dynamic response of the missile during a helicopter launch. The modeling focus began with rigid body dynamics, but quickly shifted to flexible body dynamics with modal testing and correlation. Modal test fixtures were built for missile and launcher testing. This paper will discuss the test fixtures relating to validating the structural dynamics model. The paper will also present an overview of the analysis, testing, fixture design and finite element model correlation as a result of this project.
