一、前言钻机刹车台架试验的目的,主要是评价刹车副的制动效能(制动力矩或摩擦系数)和使用寿命(磨损率),并测定其热载荷特性。到目前为止,在国内还不能进行这种试验,因而不得不用实物直接在油田的钻机上进行试验。虽然试验条件就是实际工况,但试验参数一般很难精确控制。各种因素也会相互影响,并且还很容易受到人们主观因素(包括操作和判断 I. INTRODUCTION The purpose of the rig test of drilling rigs is to evaluate the brake efficiency (braking torque or friction coefficient) and service life (wear rate) of brake pairs, and to determine their thermal load characteristics. Until now, such tests have not yet been carried out domestically and have had to be tested in kind on rigs in the field. Although the test conditions are the actual conditions, but the test parameters are generally difficult to accurately control. Various factors also influence each other, and are also susceptible to subjective factors (including operation and judgment
