Evaluation of Dynamic Environmental Adaptability of Space-borne DIP PROM Components

The dynamic environmental adaptability of a space-borne DIP PROM compo- nent was investigated using the method of mechanical analysis and verification test. The me- chanical test items and test levels were determined by the component＇s dynamic environmental sen- sitive factor analysis, and the engineering prototype was designed. By the mechanical analysis us- ing simulating toolkit, the response state and characteristics of the component were predicted, and the proper installation of the accelerometer was determined. From the results of the evaluation test, the installation of the accelerometer was justified, and the component＇s dynamic environmental adaptability was eoncluded. The evaluation process praeticed provides reference for the follow-up dynamic environmental adaptability research of other spaee-borne eomponents.
