Beschreibung
Zusammenfassung:	The utility model discloses a test device for automatically measuring the friction coefficient of a model material, which comprises a fixed base and a support plate, a movable hinged support is fixed at one end of the fixed base, one end of the support plate is rotatably connected onto the movable hinged support through a rotating shaft, an angle sensor is arranged on the support plate, and a gradienter is arranged on the upper surface of the support plate. A lifting device is arranged between the fixed base and the supporting plate; a movable baffle and a fixed baffle are sequentially arranged on the supporting plate in the direction close to the movable hinged support, the fixed baffle and the movable baffle are used for clamping a footwall rock mass of the model block, a dial indicator is installed on the fixed baffle, and a sensing probe of the dial indicator is used for making contact with an upper footwall rock mass of the model block so as to carry out shear slip detection. The influence of the test de
