Abstract. Requirements to a method of a time estimation before the fatigue failure of radioelements (RE) outputs are formulated at vibration effects. The hierarchical approach is put in a basis of a method of time estimation before fatigue failure of RE outputs. A construction of the block is subdivided on the structural levels of breaking up into smaller units. Designed calculated models are put in foundation of the automized subsystem for the analysis and security of time before fatigue failure in constructions of onboard radio-electronic equipment at vibrational actions and are used for an time estimation before fatigue failure of RE outputs.

Keywords: Radioelements outputs, fatigue failure, harmonious, casual vibration, fluctuations, pressure, dynamic influences.
