Abstract.

Purpose of this study was to design a model of interaction between falling rock lumps and movable operating elements of a vibratory machine and to determine rational and optimal factors for the stress state of the surface under protection or deformation of the lining.

The previous studies showed that the main factors which influenced protective properties of the lining were the lining thickness and hardness and impact force, however, they did not take into account a combined effect of changes in the rubber lining area or dilatation modulus. The experimental data obtained previously were analyzed in regression with the help of an applied package for processing statistic data SPSS Statistics and by least-squares method. Regressive dependencies between the stresses occurred in the box and indentation depth and parameters of the protective rubber lining (its firmness and area) and impact energy were established with high level of confidence and adequacy of simulating lumps falling on the movable operating elements in the mining machines. The mathematical model can specify rational and optimal factors for the stress state of the surface under protection or deformation of the lining.

Keywords:

 rocks, elastic lining, impact, stress.
