             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
