Zusammenfassung:The invention discloses a variable inclination angle cyclic loading test system and a contact fatigue and critical load test method, and relates to the technical field of contact fatigue testing machines. The method solves the problem that the existing solid film performance test method can only compare test data such as critical load to judge the bonding performance of a film-substrate system, but cannot realize comprehensive quantitative characterization analysis of the fatigue bearing performance of a hard solid film on the surface of bearing steel. A servo motor is installed at the top of a vertical sliding table, an electromagnetic vibration exciter is in sliding connection with a sliding rail of the vertical sliding table, a loading head is installed on a main shaft of the electromagnetic vibration exciter, the vertical sliding table is installed on an optical platform, and a three-dimensional force sensor, an x-axis angular displacement table, a y-axis angular displacement table and a plane sliding tab
