REGRESSION ANALYSIS DEPENDENCE OF THE FORCE ON THE AREA OF INDENTATION AND HARDNESS LININGS VIBRATOR

In the article the analysis of experimental data obtained during the test vibrators. The article, based on regression analysis of the experimental data the dependence of the force pressing on the parameters (area and hardness) of the rubber lining. Dependence characterizes the load capacity in the field of linear deformation of rubber. It is shown that the increase in the area of the rubber layer increases the effect of the influence on volumetric compression deformation of rubber, which, in turn, reduces the thickness of the protective lining.
Considered a positive impact rubber lining to reduce shock loads to protect metal surfaces with proper choice of the thickness of the rubber layer. The magnitude of thickness of the rubber layer should correspond to the maximum impact energy, and at the same time, in the contact area undergoes a deformation of not more than 20% of its thickness (linear crumple zone) to prevent the breakdown of the rubber. The article presents the solution of the contact problem shock piece of rock on the rubber lining and determined allowable strain on the area of the collision. The calculations used a static or dynamic Young’s modulus for rubber.

Keywords
