Vibration analysis of a multipurpose platform
Abstract
Some results are presented of the vibration analysis for simplified models of a multipurpose geostationary platform. For the detailed analysis, the finite element method is widely used, but in a preliminary analysis the method described here is also useful since it is computationally tractable and easy to handle although there are constraints on the configuration complexity. A mission model is described for the proposed platform containing six missions of communication and broadcasting. Launch sequences and deployments of the platform, and mass and inertia properties of the constitutent modules are briefly explained. The analysis procedure is presented together with the simplifing assumptions and the main results. The analysis are performed not only for the final platform of cross type and T-letter configuration but also for the interim stages of construction. The results are shown in figures with numerical tables.
