The development of technology of microsatellite represent simiral benefit which one of the technology choice that will offering function same as conventional satellite in general. Small, expeditious in course of making, and cheaper are representating the ability of microsatellite which will be on the market development.<p>The microsatellite design as an unity of the iteration process integrating of many subsistem. Bus of microsatellite, are the main structure that will bring sensitive apparatus and equipments, It have to be designed with perfection and standardization to emerging protection of vibration effect that happened which effected by impeller of laucher rocket.<p>This Final Project elaborating static in order to evaluating response when structure get accelaration load. Dynamic analysis is also conducted on bus structure. Module of bus structure is effected by vibration that happened by launcher vehicle, furthermore dynamic input syle will be vary, hence the anlysis will be conducted by using assorted kind of dynamic input type. Bus structure modeling are conducted by MSC. Nastran which can analyse the element of the structure, the entire static and dynamic analysis will be solve.<p>Bus structure of Ganesyasat microsatellite made by Alumunium plate Al 7075-T6, with eight parallel module. Axial and of lateral load given 16.6 g and 12 g. Finite element method evaluated that bus structure have conducted of axial and lateral load combination, with maximum and yield stress are 216.666 MPa and 503 MPa. The value of eigenfrequency from the dynamic analysis indicating that bus structure have natural frequency natural in axial and lateral direction that are 95.552 Hz and 31.63 Hz.<p>First Module, if model have excitated with oscilation input of highest natural frequency 344,931 Hz, hence the structure will oscilating with 3.9 g accelaration, this value would be happen at launching time.<p>Seventh Module, if model have excitated with oscilation input of highest natural frequency 116,748 Hz, hence the structure will oscilating with 0.8 g accelaration, this value would be happen at launching time.
