PROBLEM TO BE SOLVED: To faithfully simulate and load an actual dynamic load and an actual static load by controlling a shaker in such a way that the measured value of a shaft-part actual model which models a bearing, to be tested, and a shaft part facing the bearing to be tested agrees with the calculated result of a shaft- part numerical model which is numerically modeled in a computer. SOLUTION: A shaft 5 which is supported by a bearing 3 and a bearing 3 is turned and driven by a driving source. The shaft part of a rotating machine system is simulated via a housing 4 and a housing 4 by a shaker 6 and an exciter 6 which are fixed to a rigid wall 12. A bearing 1, to be tested, which is inserted and mounted near the center of the shaft 5 is housed in a housing 2, and the measured value of a reaction force which is measured by a measuring device 7 is input to a computer 11. Then, the computer 11 inputs a shaking signal to a control device 8 for the shakers 6 via a signal transmission means 17 in such a way that the measured value of a shaft-part actual model which models the bearing to be tested and a shaft part facing the bearing to be tested agrees with the calculated result of a shaft-part numerical model which is numerically modeled in the computer 11, and the shakers 6 are controlled.
