Intelligent bypass formula viscous damper that stromatolite piezo -actuator adjusted

The utility model relates to an intelligent bypass formula viscous damper that stromatolite piezo -actuator adjusted, include the cylinder and be located the piston of cylinder, promotion piston motion's guide arm, the guide arm with piston fixed connection, master cylinder and vice jar, the inside viscous liquid damping material that is equipped with of cylinder are separated into to the cylinder, by -pass line has on the cylinder, by -pass line's both ends mouth all with the master cylinder intercommunication just communicates the position and is located respectively the piston both sides, by -pass line has regulation portion, installs stromatolite piezo -actuator in the regulation portion, regulation portion is in the drive of stromatolite piezo -actuator is adjusted down by -pass line's circulation pipe diameter. The utility model discloses the skewing influence can be reduced and the power output is improved to satisfy the demand of civil engineering shock attenuation control under seismic?action. 本实用新型涉
