Abstract

The experimental and calculated studies of the dynamic characteristics of the deflectable surfaces with the shifted support are carried out. It is found that the displacement of support leads to initiation of dry friction forces and as a result to the increase in the resonant speed and distortion of phase portraits of forced vibrations of surface. The results of the work can be used to identify the axis misalignment of the control elements supports according to the results of the resonance tests of aircrafts.
