FIELD: testing equipment. SUBSTANCE: elements of structure are subjected to asymmetric static loading with simultaneous loading by casual stationary vibration process. Mean-time- between-failures, moment of destruction of tested elements, stresses and vibration overloads are found. Obtained values are used to calculate equivalent for computation of lifespan of elements of structures of objects of aviation rocket armament under conditions of operational loads in accordance with design formula. EFFECT: increased precision of determination of lifespan of aviation rocket armament. 1 tbl
