The efficiency assessment of acoustic quality monitoring application for research of damages, in particular, the cracks arising at long operation of the heat power equipment is resulted in the present work. The differential equations were first derived describing the change in time delay of surface acoustic waves in the vicinity of the crack, which are directly depending on: a) the argument; b) the plane of states in an implicit form from the parameter of model; c) on a plane of conditions for logarithmic characteristics. |
