The invention relates to a simulation test method of a rotating outer ring/fixed inner ring rolling bearing. The bearing test device is composed of a drive motor (1), a coupling (2), a rear pivot bearing (3), an outer ring shaft (4), a front pivot bearing (5), a sliding guide rail (6), a loading hydro-cylinder (8), a hinge I (9), an inner ring shaft (10), a hinge II (11), a spring (12) and a loading sleeve (13), wherein the outer ring of a test bearing (7) is installed in a cantilever end outer sleeve of the outer ring shaft; the inner ring of the test bearing is installed on the inner ring shaft; the inner ring shaft is fixed on the loading sleeve; the loading hydro-cylinder directly loads the test bearing in the radial direction by using the loading sleeve; and the axial holddown spring, the sliding guide rail, the hinge II and the like are utilized to realize axial positioning of the test bearing and reduce the interference of the radial force, thereby completely simulating the simulation test method of th
