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.RASAT, which is the first micro satellite designed and manufactured in Turkey, has a finite element mesh model. First, modal analysis was run and modal frequencies and mode shapes were evaluated. Then, sinusoidal and random vibration analyses were conducted in order to observe the response of the RASAT structure to these dynamic conditions.RASAT has SQM, on which dummies of main flightidentical structural elements and electronic component and harness are placed. Various ground vibration tests are conducted on RASAT SQM aiming to observe the real satellite modal frequencies and dynamic responses.In order to verify the finite element model and check the structural integrity, the results of vibration tests were compared with the analysis results. As similar to vibration tests, from the analyses run, the responses of the corresponding nodes for accelerometer locations were recorded. In other words, the frequency response functions are determined in X, Y, Z directions after the analyses. Those two results were compared and the differences and deviations were observed. According to these outcomes, some comments on whether the finite element model was sufficiently good or not and the other possible reasons for these differences and deviations were summarized
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
