Evaluation and comparison of finite element dynamic analyses and vibration test results of structural model of RASAT satellite

摘要

This paper describes the comparison of the finite element dynamic analyses and ground vibration test results of the RASAT Structural Qualification Model (SQM), and evaluation of those. Satellite structures and subsystems are exposed to extremely high dynamic conditions during launch. In order to observe the survivability of satellite structure, various methods are evaluated. Main methods are structural finite element analysis and ground vibration testing.
