Dynamics of vibration excitation and prospects of dynamic investigation of power equipment of nuclear power plants using the resonance method

Differential equations of vibrations of the vibrator-object system were obtained by solving Lagrange equations of the 2nd kind. During the vibration of a 400 kg test body over the 1 to 90 Hz frequency range of the vibrator, the calculated time of vibration stabilization did not exceed 10 s, which is consistent with experimental results. The method enables one to determine the material compliance during actual seismic events and during the additional diagnostics of the equipment. (J.B.). 1 ref
