Оптимизация геометрии режущих элементов вооружения породоразрушающего инструмента

Abstract

Interaction of working parts rockdestractive tools with the rocks in the drilling work process has been considered. Mechanical model of loading of working parts have been made up. In accordance with corresponding boundary and initial conditions mathematical model of the interaction process has been developed and solved on the basis of this model. As a calculating procedure variation method of conditional oplimizalon has been applied. As a result methods determining optimal form of working parts providing maximum destructive power and minimum energy intensity have been developed.
