METHOD DETERMINING FREQUENCY CHARACTERISTICS OF STRUCTURAL MEMBERS OF CONSTRUCTION Russian patent published in 2002 - IPC

Abstract RU 2179309 C1

FIELD: vibration testing technology, determination of frequency characteristics of multimember structures. SUBSTANCE: proposed method determining frequency characteristics of structural members of construction consists in measurement of proper values of inherent and mutual spectral densities of power of response of construction to applied vibration action in first units of joint of structural members of construction and in second units which are adjacent relative to first units and in subsequent determination of values of complex frequency characteristics of structural members of construction obtained by results of solution of system of equations. EFFECT: increased informativity of determination of frequency characteristics of multimember construction thanks to determination f frequency characteristic of each individual member of it. 2 dwg
