Analytical estimation of inertial properties of the curved rotating section in a drill string

Autor: Grydzhuk, Jaroslav, Chudyk, Igor, Velychkovych, Andriy, Andrusyak, Andriy

Publikováno v: Eastern-European Journal of Enterprise Technologies, Vol 1, Iss 7 (97), Pp 6-14 (2019)

We have proposed approaches to analytical assessment of the moment of inertia related to the curved rotary sections in a drill string. Research into rotation processes of the curvilinear sections in a drill string is associated at present with a part
