BED TESTING ARTICLES FOR COMPLEX ACTION OF VIBRATION AND LINEAR ACCELERATIONS

摘要

FIELD: testing equipment. SUBSTANCE: given bed relates to equipment for dynamic testing of articles. Invention is aimed at approximation of testing conditions to operational ones due to provision of variable angle between vectors of vibration and linear accelerations and between vector of vibration acceleration and coordinate axes of article. Bed presents combination of vibration exciter 3 and centrifuge which rotor 5 is mounted on mobile part of vibration exciter. Tested articles 6 are anchored on rotor. Specified variable angle is ensured as rotational axis of rotor is perpendicular to working axis of vibration exciter. EFFECT: approximation of testing conditions to operational ones. 1 dwg
