The invention discloses an intelligent rotation shaft dynamic regulator. The intelligent rotation shaft dynamic regulator comprises a sleeve (2), wherein a rotation shaft (1) is arranged in the sleeve, a plurality of sleeve through holes (7) and a plurality of sleeve threaded holes (12) are formed in the sleeve along a circumferential direction at equal distance and in a staggered way, a stop support (3) is arranged at a position, corresponding to each sleeve threaded hole, of an outer wall of the sleeve, a support bolt (11) is inserted to each stop support and the corresponding sleeve threaded hole in a penetrating way, an end part of an inner side of the support bolt is fixedly connected with one end of a connection support seat (14), the other end of the support seat is fixedly connected with an elastic pad (15), an inner side surface of the elastic pad is in direct contact with an outer wall of the rotation shaft, an adjustment bolt (8) is arranged in each sleeve through hole in apenetrating way, each adjustment bolt penetrates through the sleeve through hole and then continues to penetrate through a piezoelectric sheet (10), and an end part of an inner side of the adjustmentbolt is fixedly connected with a self-aligning block (4). Real-time adjustment of a mass center of the device can be achieved by the inherent characteristic of a piezoelectric intelligent material.
