SMA piezoelectric friction intelligent mixed damper
The invention relates to an SMA piezoelectric friction intelligent mixed damper, and belongs to the field of energy consumption and seismic mitigation of civil engineering structures. The intelligent mixed damper comprises a damper box, a piezoelectric ceramic driver box with a piezoelectric ceramic driver is arranged in the damper box, a left baffle is arranged at the left side of the piezoelectric ceramic driver box, a right baffle is arranged at the right side of the piezoelectric ceramic driver box, and multiple SMA filaments are arranged between the right side wall of the piezoelectric ceramic driver box and the side wall of the damper box as well as between the left baffle and the right baffle; an actuating rod sequentially penetrates through the left side wall of the damper box, the left baffle and the left side wall of the piezoelectric ceramic driver box and then is fixed to the left end of a sleeve in the piezoelectric ceramic driver box, the left end of a connecting rod is inserted from the right end of the sleeve, and the right end of the connecting rod is fixed to the right baffle. The intelligent mixed damper is convenient to machine, high in energy consumption capacity and capable of combining semi-active control and with passive control to be applied to the field of energy dissipation and seismic mitigation more efficiently and has self-resetting capacity.
