Abstract
The space to earth observation small satellite borne smart integration design was studied, combined with the engineering practice, the structure design of a dexterous small satellite. The organic combination of load structure and satellite structure together, and full consideration was given on the integration of design, structure and layout of the whole satellite cable, satellite integrated design of satellite structure and the entire star passive thermal control, the function density of the whole satellite was improved, onboard single computer layout was optimized, the entire star quality was effectively reduced, compression volume, and lower launch costs application were completed. Design and analysis results show that, the natural frequency of the entire star x is 56.465 Hz, the natural frequency of y is 59.704 Hz, the natural frequency of z is 218.88 Hz, the whole star high stiffness lay the foundation on fast mobile imaging smart satellite; large safety margin is reached 3.85 with random response and sine response in the controllable range, can withstand complex mechanical environment from transport to various emission process; satellite high functional density, passive thermal control design makes the whole satellite thermal control resources small power consumption with high space utilization rate, simple and convenient cable layout.
