The analysis of limiting states of power system of "45 carbon steel - siluminum" at frictional and mechanical fatigue on energetic criterion
The results of mechanical test for the active system “the cylindrical specimen of 45 carbon steel and it is a counter body as a partial liner from siluminum” at frictional and mechanical fatigue are given. Curves of mechanical fatigue and frictional and mechanical fatigue by the criteria of achieving the maximum permissible wear are constructed for this system. The main characteristics of frictional and mechanical fatigue resistance for the studied active system are obtained. The main provisions of the energy theory of limit states of active systems of machines and equipment are given. The values of the required parameters and coefficients for the studied active system are defined and the analysis of the obtained experimental results by using the energy criterion of limit states is made. It is shown that the energy criterion permit to describe satisfactorily the state of the active systems which operate at a frictional and mechanical fatigue.
