METHOD DETERMINING DYNAMIC LOADS

FIELD: technical measurement during tests of various types of machines and structures, structural mechanics, tests of strength of various materials. SUBSTANCE: amplitude of movements caused by family of unknown forces in points of application of family of known outside forces and amplitudes of movements caused by family of outside known forces in points of application of family of unknown forces are measured. Measurements are carried out on each specified frequency, phases of movements of each point and phase of each force of known family are measured in addition. Amplitudes of forces of unknown family and their phases are found from mutuality relations of possible complex works, from mutuality of individual complex movements, from mutuality of individual complex reactions, from mutuality of individual complex reactions and movements. EFFECT: measurement of amplitude and phase of unknown dynamic and generalized dynamic loads acting on indefinable systems and systems with distributed parameters as well as amplitudes and phases of reactions with accuracy determinable by precision of measurement equipment only. 3 cl, 1 dwg
