Embodiment Construction

[0022] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0023] combine figure 1 ~4, the structure includes spring steel sheet 1, coil fixing tool 2, upper base plate 3, angle aluminum 4, aluminum plate 5, mass block 6, mover 7, excitation coil 8, stator 9, excitation coil 10, flange-shaped shaft Seat 11, guide shaft 12, linear bearing 13, double-ended stud 14, base 15, long bolt 16, three-hole aluminum sheet 17, locknut 18, screw 19.

[0024] The characteristics of each part are mainly reflected in:

[0025] The shock absorber is supported by spring steel sheet 1, which has high lateral rigidity and good stability. Holes are drilled on the spring steel sheet, and the left and right sheets are bent into a semicircle, and are clamped and connected by bolts at the joint through the upper and lower splints. The mass block 6 can be fixed with bolts on the top of the upper bottom plate to roughly adjust the frequency. Th...

Abstract

The invention provides a semi-active / full-active integrated type electromagnetic vibration absorber which comprises spring steel sheets, two rotors, two stators, an aluminum plate and a base. The upper end portions and the lower end portions of the two spring steel sheets are respectively fixed together to form a spring outer shell, wherein the two sides of the spring outer shell are arc in shape, and the middle of the spring outer shell is a line segment. The upper end portions of the two spring steel sheets are fixed together through an upper bottom plate, and the lower end portions of the two spring steel sheets are fixed together through a lower bottom plate. The aluminum plate and the upper bottom plate are fixed through an angle aluminum piece, the lower end of the aluminum plate and a guide shaft are fixed, the guide shaft is inserted into a linear bearing, and the linear bearing is fixed in a base. The two rotors are reversely fixed to the aluminum plate and located on the two sides of the aluminum plate respectively, the portions, on the two sides of the guide shaft, of the base are respectively provided with a stud, the two stators are arranged on the two studs respectively, the two stators and the two rotors are arranged in an opposite mode, exciting coils are wound on the rotors, and magnet exciting coils are wound on the stators. According to the semi-active / full-active integrated type electromagnetic vibration absorber, switching of semi-active operation and full-active operation can be achieved.

Description

technical field [0001] The present invention relates to a shock absorber, in particular to a power plant shock absorber. Background technique [0002] Vibration is a common engineering phenomenon, such as mechanical vibration caused by centrifugal force imbalance in rotating machinery. Moreover, most machinery and equipment in engineering practice have the characteristics of frequency conversion. The dynamic vibration absorber changes the distribution and transmission characteristics of the vibration energy of the system by attaching a substructure to the structure that needs vibration reduction (called the main system), so that the vibration energy is transferred to the additional substructure, so as to control the vibration of the main system. Purpose. [0003] The traditional dynamic vibration absorber is mostly passive control, which has a good vibration absorption effect on the narrow-band response of the main system, but because its vibration absorption bandwidth can...
