The application discloses a self-adaptive vibration isolation control method for a phase-separated closed bus, and is characterized in that an equivalent fourteen-degree-of-freedom vibration isolation system dynamic model is established in combination with the internal structure of the phase-separated closed bus and the phase interval installation mode of a magneto-rheological elastomer vibration isolator; after input and output variables of the dynamic model are determined, a fuzzy controller is designed, the input variables are fuzzed, fuzzy rules are formulated, and output variables are obtained after defuzzification; and the quantization factor parameters of the fuzzy controller are determined, the calculated control current is output to the magneto-rheological elastomer vibration isolator, and the stiffness and damping of the vibration isolator are changed. The self-adaptive vibration isolation control method can fully exert the mechanical characteristics of variable stiffness and variable damping of the magneto-rheological elastomer vibration isolator, efficiently suppress the vibration generated under normal working and short-circuit current conditions of the phase-separated closed bus, and has important practical significance for ensuring the safety of equipment and the stability of a power system.

This application discloses a small inertial exciter, which includes a movable part, a fixed connection part, and a support part. The fixed connection part is located above the movable part and is connected to it via the support part. The support part is equipped with a coil, the fixed connection part is equipped with a magnet, and the movable part is equipped with a spring. The coil moves under the action of current, causing the spring to move, and the displacement is transmitted to the outside through the inner and outer studs of the fixed connection part. This small inertial exciter can output a large inertial force at low and low-to-medium frequencies.

This utility model relates to the field of bamboo-wound composite pipe gallery technology, specifically an internal support for a bamboo-wound composite pipe gallery, comprising: a pipe frame for supporting the internal pipelines of the bamboo-wound composite pipe gallery; a support unit connected to the pipe frame; and an air pump connected to the support unit. The assembly consisting of the support unit, pipe frame, and air pump provides a stable and reliable internal support structure for the bamboo-wound composite pipe gallery. The inflatable rubber component in the support unit reduces friction and wear between the internal support structure and the inner wall support of the pipe gallery, while also better complementing the deformation resistance of the bamboo-wound composite pipe gallery. During thermal expansion and contraction, the inflatable rubber component in the support unit enhances the elastic buffering effect of the internal support and fills the gaps between the support and the inner wall of the pipe gallery during expansion, reducing vibration displacement and significantly increasing the stability of the pipelines within the bamboo-wound composite pipe gallery.
