abstract = "An Optical Solar Reflector (OSR) was developed in Brazil as an
alternative to be used in the thermal control subsystem of the
program: China-Brazil Earth Resources Satellites (CBERS). The
mechanical vibration is one of the mandatory tests for qualifying
the OSR and its installation process. To perform mechanical
vibration tests in the OSR, a structural dynamic analysis was made
to estimate the vibration environment at the established
attachment areas in the satellite. The finite element model of the
satellite was used; applying to its base a random vibration
excitation extracted from the CBERS 3 and 4 Environmental
specification. The responses in the OSR installing areas were
determined. These analyses results including a standard
specification for electronic components were used to establish an
envelope to qualify the OSR. The enveloped mechanical vibration
environment was used in the OSR tests in the electromechanical
shaker whose results showed the manufactured OSR can be included
as an option to be used as a method of the satellite thermal
control.",
