Research of the wear mechanism the rubber lining mining trucks

Abstract

The rubber lining used to protect the bodies of mining trucks is characterized by impact at an angle to the surface of the lining. Described experimental installation, allowing to model the impact of single solid parti-cles at an angle to the surface of the rubber. It is established that the basis of the mecha-nism of the fracture of rubbers under oblique impact is cracking. The development direc-tion of cracks is approximately equal to the angle of attack, i. e. the direction of the force of impact. The destruction is cyclical in nature and follows the scheme: the tear of the surface - rip crack - turn cracks and separation of the fragment. Factors determining the length and depth of the development of the initial crack set
