Mechanical Environment Analysis and Test Validation of the Side-mounted Satellite and Dispenser Integration
For newly-developed side-mounted satellites and dispenser system,how to determine mechanical environment analysis and test validation state must be considered in the early development period.The vibration response analysis is respectively conducted for the satellite and dispenser integration and for the single satellite.It is indicated that the dispenser amplifies the sinusoidal vibration which is from the dispenser lower end frame to the satellite and dispenser interface,but attenuates the random vibration.The dispenser affects the vibration response of the satellite and dispenser interface,and the satellite units.According to the analysis results,the validation scheme is formulated that the integration of two side mounted satellites and dispenser is analyzed and validated for mechanical environment in the development phases by the satellite and rocket contractors.The satellite and dispenser integration is checked by mechanical tests and launched into orbit successfully now.It is verified that the mechanical analysis and test of the satellite and dispenser integration are effective.
