Claims (2)

1. Способ неразрушающего контроля качества железобетонных конструкций балочного типа, заключающийся в установке конструкции на стенде, закреплении ее концов согласно условиям эксплуатации, возбуждении в конструкции колебаний на резонансной частоте, измерении этой частоты и декремента вынужденных колебаний, сопоставлении этих динамических параметров с соответствующими параметрами эталонной конструкции заданного типа при тех же режимах контроля и условиях закрепления, и определении по результатам сравнения показателей качества контролируемого изделия, отличающийся тем, что для контролируемой конструкции производят спектральный анализ колебательного процесса, определяют первые четыре амплитуды колебаний и по ним вычисляют коэффициент нелинейных искажений.1. The method of non-destructive quality control of reinforced concrete structures of the beam type, which consists in installing the structure on a stand, securing its ends according to operating conditions, exciting vibrations in the structure at a resonant frequency, measuring this frequency and decrement of forced vibrations, comparing these dynamic parameters with the corresponding parameters of the reference structure of a given type under the same control modes and fixing conditions, and the determination of roliruemogo products, characterized in that the structure for controlled produce vibrational spectral analysis process determines the first four oscillation amplitude and it is calculated THD. 2. Способ по п.1, отличающийся тем, что коэффициент нелинейных искажений определяют при разных уровнях энергии возбуждения поперечных или продольных колебаний, строят графики «коэффициент нелинейных искажений - энергия вибровозбуждения» для эталонной и контролируемой конструкций и оптимальный уровень энергии возбуждения колебаний находят по максимальному расхождению этих кривых на начальном участке стабилизации.2. The method according to claim 1, characterized in that the non-linear distortion coefficient is determined at different levels of excitation energy of transverse or longitudinal vibrations, graphs are constructed "non-linear distortion coefficient - vibration excitation energy" for the reference and controlled structures and the optimal level of vibration excitation energy is found from the maximum the discrepancy between these curves in the initial stabilization section.
