Modeling Of Loads On Cutting Elements Of Drill Bits

摘要

A new approach to modeling of the work performed by cone drill bits at the face is outlined. A virtual model of the dynamic force interaction between a cone drill bit and the face of the hole is proposed. The ADAMS software package is used for the modeling with consideration of frictional forces in the sliding supports, the frictional forces of the equipment components, and the depth of their embedment in the rock. The dynamic forces acting on the teeth during rotation of the cutters, and the distribution of average loads around the rings and cutters of the bit are obtained. The possibility of using the model developed to optimize parameters of bit equipment is demonstrated.
