Ispytanie radioälektronnoj apparatury i eö komponentow

Konstrukcii RJeA i eö i komponenty, rabotaüschie w uslowiqh wibracionnyh i akusticheskih nagruzok, dolzhny bezotkazno rabotat' w ozhidaemyh uslowiqh, sootwetstwuüschej trebowaniqm nadözhnosti dlq apparatury w celom. Problema predstawlqet slozhnost' w widu sluchajnogo haraktera wibracionnyh i akusticheskih nagruzok.Dlq podtwerzhdeniq trebuemoj nadözhnosti neobhodimy mnogochislennye i slozhnye laboratornye ispytaniq. Ocenka prochnosti i ustojchiwosti älementow konstrukcii RJeA osnowywalis' na ustalostnyh harakteristikah materialow. Metody ocenki wibracionnogo powrezhdeniq konstrukcii oceniwalis' äxperimental'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
