Ispytanie radiojelektronnoj apparatury i ejo komponentov

Konstrukcii RJeA i ejo i komponenty, rabotajushhie v usloviyah vibracionnyh i akusticheskih nagruzok, dolzhny bezotkazno rabotat' v ozhidaemyh usloviyah, sootvetstvujushhej trebovaniyam nadjozhnosti dlya apparatury v celom. Problema predstavlyaet slozhnost' v vidu sluchajnogo haraktera vibracionnyh i akusticheskih nagruzok.Dlya podtverzhdeniya trebuemoj nadjozhnosti neobhodimy mnogochislennye i slozhnye laboratornye ispytaniya. Ocenka prochnosti i ustojchivosti jelementov konstrukcii RJeA osnovyvalis' na ustalostnyh harakteristikah materialov. Metody ocenki vibracionnogo povrezhdeniya konstrukcii ocenivalis' jexperimental'no i teoreticheski. The design of radioelectronic equipment and its components working in the conditions of vibration and acoustic loads must work without failures in the expected conditions corresponding to reliability requirements for the equipment on the whole. The problem is complicated due to random character of vibration and acoustic loads.To confirm the required reliability multiple complicated laboratory tests are needed. The assessment of durability and stability of the elements of radioelectronic equipment design was based on fatigue characteristics of materials. The methods
