INTENSE THE DEFORMED CONDITION THE destroying tool FOR CRUSHING OF oversize ROCKS AT DYNAMIC LOADING
Distribution of tension in time in shock part of the tool set in motion the diesel by a hammer at crushing of an oversized piece of breed is considered. It is accepted that the contact part of the destroying tool represents an ellipsoid which big axis has the constant radius of curvature equal to 220 mm. The sizes of a small axis as it is established by calculation on static durability taking into account efficiency of contact influence when crushing a stone 3,5 times smaller. The solution of a dynamic task of the theory of elasticity is carried out by a numerical method of final elements with use of the program ANSYS/LS DYNA complex.
