Автоматизированная система определения остаточных напряжений в авиационных деталях и деталях с покрытиями

Abstract

One of the important economic indicators of aviation technology is its resource and reliability. To increase these qualities, hardening technologies based on the surface plastic deformation of critical parts are widely used in the aircraft industry. To assign effective hardening regimes, it is necessary to control the residual stresses in the surface layer of the parts. This is especially important for thin-walled parts, for which effective hardening regimes must provide not only increased fatigue resistance, but also geometric accuracy. This paper presents an automated system ASB-1 that allows to investigate the residual stresses in critical parts of aviation equipment.
