Fundamental Frequency Decomposition of Slender Structures on a Self-Tandem Dual Satellite

In order to make full use of the carrying capacity rocket and reduce invalid mass satellite, first-order fundamental frequency self-tandem dual satellite should be effectively decomposed into designed each satellite. this article, is analyzed based on beam theory slender structure arranged in tandem Rayleigh–Ritz theory. The influence stiffness ratio, size ratio also discussed. Based results, decomposition method index proposed, taking consideration manufacturing error joint between satellites. numerical simulation verified against experiments, setting same platform different platforms. results show that can decompose a result within required range, less than 6.5%. calculation improve specific functional density reducing overall development risk.
