Abstract

The method of vibrating diagnostics offered in given work, is based on harmonious excitation of turbomachinery blades and definition of the dynamic response in some point. The used equipment of vibrating excitation influences investigated object the concentrated force, or creates kinematic excitation. In this connection the special attention is given equivalent weights of an elastic body with parametre of excitation «kinematic». Considering features of the used vibrating measuring equipment, as supervision parametre vibrating moving and vibrating pressure here are considered.
Keywords

equivalent weights, dynamic compliance, natural modes of oscillations
