Abstract: On the principle of systems
analysis and the failure analysis of drilling rigs' brake
pairs, a matrix representation was presented, in which the main
factors effecting on the wear characteristics of the brake pairs
regarded as a tribo-system have been found to be the frictional
heating at the interfaces between the brake blocks and rim and
the matching character of the materials of brake pairs.
Correspondingly, two measures have been described. The one is
rationalizing of operating mode or optimizing of design
parameters of the brake pairs by means of a group of
theoretical heating-up characteristics curves, the other is
screening out the optimum pairing of the materials of brake
pairs based upon a series of simulation laboratory tests.
