Simulated impact type comprising a frame (100), a specimen case assembly, an X-axis direction loading mechanism, a Y-axis direction loading mechanism, a Z-axis direction loading mechanism mounted on the frame (100), and a control system Rock experiment equipment. The loading mechanism in each direction is provided in alignment with four columns (11, 21, 31) arranged in a rectangular shape, and fixed to both ends of the four columns, respectively. Frame (12, 22, 32) and second frame (13, 23, 33), loading hydraulic cylinder (14, 24, 34) and lead screw (15, 25, 35) can apply a static load stress and a disturbance load to a rock specimen in three directions perpendicular to each other in a three-dimensional space, and can be used for a simulated impact type rock experiment. And the configuration of the three sets of loading mechanisms is largely identical, has excellent symmetry, and loading static load stress or disturbance load in these three directions of the rock specimen For the operation, it is possible to further easily and precisely controlled.
