Research of mine imitator interaction with deformable surface

Abstract

The processes of the mine imitator interaction with deformable surfaces of the soil are analysed in the paper. Using the explicit code LS-Dyna v.971 deforma-tions of the detonator cap of the imitator due to the interac-tion with soil at different firing speeds and their character-ristics were determined. The reliability criterion of the detonator’s operation was proposed – the minimum of dis-sipated energy during cap – soil interaction and structure of the cap was proposed. The results of the interaction com-puter modeling were verified by experiments and field tests.
