| Abstract: |
| Objective To adapt to the “productization” development trend of satellite integrated electronic system and divide the traditional instrument-oriented environment test to functional modules. Methods Finite element models on integrated electronic instrument and module were established to have simulation analyses on dynamics, thermodynamics, etc. Input conditions in module test were obtained based on if the key components of function module could achieve the setting standard for instrument-oriented test Results With random vibration test as example, the FEM analysis showed that the mechanical settings of each direction should be x 18.06 g\y 15.07 g\z 15.54 g, to meet the equal setting qualification standard as 14.33 g for the instrument-oriented test. Maximal responsibility from function module was collected while carrying out the environment test on ACT2000 vibration machine. The maximal mechanical responsibility error was 6.31%, which met the demand for engineering error analysis (less than 10%). Conclusion Environmental test based on integrated electronic function module can meet the setting standard for instrument-oriented test. It is easier to find out design defect in an early phase, so to reduce research and development cost. |
