the Response of change of resistance to presence of artefacts of surfaces

The adhesive adhesion, presence of defects of surfaces (for example, cutting or wavinesses of the higher usages), cavitation processes is the origination reason vibroudarnogo a regime at which the planimetric square of contact tested tribosoprjazhenija varies and, as consequence, a pure resistance at use of an electroresistance method.

In drawings 4.15, 4.16 samples of signals of resistance and the enclosed loading on examinees installations - cups №3 and heads №4 of table 37, displaid for every minute tests are resulted.

Drawing 4.15 - the resistance Response at vibroudarnom a regime: 1 - an initial signal; 2 - a signal rebuilt with the help vejvlet -

Transformations

Drawing 4.16 - the resistance Response at vibroudarnom a regime: 1 - an initial signal; 2 - a signal rebuilt with the help vejvlet -

Transformations

For the best visualisation of fluctuations of resistance at vibroudarnom a regime according to drawings 4.15, 4.16 initial signals (1) are rebuilt by means of vejvlet-transformation to a frequency range f = 1,4... 5,9 kgts in signals (2). Origination vibroudarov surfaces coincides with fluctuations of resistance and the enclosed loading that testifies to determination of experimental functional dependence between resistance and artefacts of friction surfaces.
