Research on Random Vibration for Satellite TDICCD Camera and Data Processing

Random vibration test of the satellite TDICCD camera is performed in this paper. Several engineering problems during TDICCD camera random vibration test were discussed and solving methods were pointed out. The relationship between the vibration environment and structural dynamic properties is analysed, as well as the vibration environment could pose the effect and hazard to TDICCD structure. In addition the testing's practical technique and the selective gist of the control methods are studied and introduced separately. Based on site-collected results of the satellite TDICCD camera vibrating signal, the paper analyzes the time-region division of vibrating signal and the selection principle of its parameters. The date analysis is carried out with signal processor and the camera's each state of parameters were obtained. Parameters of the block's dynamic characteristic can provide us a reliable reference to satellite TDICCD camera's antivibration and vibration isolation. These also are used as modification and scientific basis for finite element calculation of camera's modality.
