step two: starting a third motor (20), controlling the up-and-down movement of a threaded sleeve (18) by utilizing the rotation of a threaded rod (19), realizing the contact of the friction plate (9) on the surface of the brake lining (10), and measuring the acting force between the friction plate (9) and the brake lining (10) in real time through a pressure sensor (12); the position of an operation table (15) is adjusted, and the real-time adjustment and control of the acting force between the friction plate (9) and the brake lining (10) are realized by combining the real-time detection of the acting force between the friction plate (9) and the brake lining (10) by a pressure sensor (12);
step three: the brake lining (10) is heated by a heating mechanism (16), and the temperature between the friction plate (9) and the brake lining (10) is detected by a temperature sensor (14), so that the real-time adjustment and control of the temperature between the friction plate (9) and the brake lining (10) are realized;
step four: the friction coefficient is calculated by a traditional friction coefficient calculation method, wherein the friction coefficient is measured by measuring the normal force and the tangential force between the friction plate (9) and the brake lining (10) through a pressure sensor (12) and by using a traditional friction coefficient calculation method, the movement track of the friction plate (9) is controlled by driving a rotating shaft (8) to rotate and driving a movable sleeve (5) to horizontally move by driving a screw rod (6) of a second motor (7), and the relative movement track of the friction plate (9) on the surface of the brake lining (10) is linear, reciprocating, circumferential or curved.
