Semi-active SMA-piezoelectric composite gear friction damper
The invention discloses a semi-active SMA-piezoelectric composite gear friction damper. The semi-active SMA-piezoelectric composite gear friction damper comprises a T-shaped connecting piece (1), annular piezoelectric ceramic drivers (5) mounted on the outer sides of gears (3), and nuts (6) for fixing each part and exerting pre-tightening force, wherein an annular friction plate (10) and the gears(3) with connecting holes are mounted at the two sides of the T-shaped connecting piece (1) through screw rods, and the gears (3) are placed at the central position of a lower connecting plate (2) with a rack and mesh with the rack; and the annular friction plate (10), the gears (3) with the connecting holes and the annular piezoelectric ceramic drivers (5) are sequentially fixed to the two sidesof the T-shaped connecting piece (1) by the screw rods (7), and the two sets of screw rods are symmetrically arranged at reserved holes in the same side of the T-shaped connecting piece (1).
一种半主动SMA‑压电复合齿轮摩擦阻尼器，包括T型连接件（1），环形摩擦板（10）和带连接孔的齿轮（3）通过螺杆安装在所述T型连接件（1）两侧，安装在所述齿轮（3）外侧的环形压电陶瓷驱动器（5），固定各个部件并施加预紧力的螺母（6）；将齿轮（3）置于带齿条的下连接板（2）的中心位置处，并与齿条啮合；螺杆（7）将环形摩擦板（10）、带连接孔的齿轮（3）和环形压电陶瓷驱动器（5）依次固定于所述T型连接件（1）的两侧，且在所述T型连接件（1）同侧预留孔处对称布置两组。
