Problems solved by technology

Although this type of damper has good vibration reduction and energy dissipation performance, due to its complex structure and high requirements for sealing and machining accuracy, the economy is generally poor
In particular, the damping coefficient of this type of damper is usually a fixed value, which cannot be adjusted or is more complicated to adjust, such as controlled by an electro-hydraulic servo valve, so its adaptability is poor
However, in some engineering applications, the damping coefficient of the damper needs to change with the change of the vibration displacement, for example, the greater the displacement, the greater the damping coefficient, or vice versa. At this time, the above-mentioned damper obviously cannot meet such use. Require

Embodiment 1

[0023] like figure 1 , figure 2 The damper related to damping and displacement of the present invention includes a damping cylinder 1, the damping cylinder is grooved, and the opening is upward. The damping cylinder 1 is equipped with an adhesive damping liquid 2, which is high-viscosity silicone oil. A movable plate-shaped moving piece 3 is provided, and the moving piece 3 is fixed on the bracket 12, and a guiding device 5 is arranged between the bracket 12 and the damping cylinder 1, and the guiding device is a one-dimensional guiding wheel rail that cooperates with each other. The two sides of the moving direction of the moving piece 3 are provided with static pieces 4a and 4b whose spacing between the moving piece 3 is discontinuously changed, wherein the static pieces 4a and 4b are fixedly welded in the damping cylinder 1, and the static pieces 4a and 4b are respectively provided with four Blocks, two blocks are symmetrically distributed along the moving direction and l...

Embodiment 2

[0028] Based on the principle of the present invention, the static plate can also be directly formed by the damping cylinder. like Figure 4 As shown, the difference from Embodiment 1 is that the driving device (not shown in the figure) of the moving piece 3 itself can realize the guiding function, so there is no need to set up another guiding device between the damping cylinder 1 and the moving piece 3 . The damping cylinder can be directly made into multiple boxes with different widths. The cylinders on both sides of the moving direction of the moving piece 3 can be equivalent to the static piece 4a and the static piece 4b. Therefore, when the moving piece 3 moves from the middle of the damping cylinder to the When moving between the stationary plates 4a or from between the stationary plates 4a to between the stationary plates 4b, the damping coefficient of the damper will increase step by step.

Embodiment 3

[0031] like Figure 5The difference between the damping and displacement-related damper of the present invention as shown in Embodiment 1 is that corrugated strips 6 are welded on the moving piece 3. This structure is conducive to further increasing the effective work between the moving piece 3 and the damping fluid 2. area, so as to ensure that the viscous damper obtains a larger damping coefficient when the size of the damping cylinder remains the same. In addition, a support plate 13 is fixedly welded on the damping cylinder 1 , and the support plate 13 is connected with the static plates 4 a and 4 b through a screw 14 . Rotating the screw rod 14 can adjust the relative position between the static plate and the support plate, and also change the distance between the static plate and the moving plate on both sides of the moving direction of the moving plate. In this case, further increase the adjustment range of the damping coefficient of the damper.

Abstract

The invention relates to a damper with variable damping coefficient used for damping and energy consumption, which comprises a damping cylinder filled with damping liquid. The damper is characterized in that the inside of the damping cylinder is provided with at least one movable moving piece; both sides along the moving direction of the moving piece are provided with static pieces, wherein the spaces between the moving piece and the static pieces are changed; and the static pieces are arranged in the damping cylinder or at least partially formed by the damping cylinder. The damper achieves the change of the damping coefficient of the damper through the change of the spaces between the moving piece and the static pieces in the moving process of the moving piece or / and the change of effective working areas, and can achieve the aim that the damping coefficient of the damper can automatically change along the displacement without complicated control mechanisms such as electrohydraulic valves, and the like, so that in many places with upward damping cylinder openings, pressure tightness does not needed to be used, thereby simplifying the structure and the processing precision of the damper, reducing the producing cost, and improving the range of application of the damper. The damper can be widely applied to the damping, buffering and energy consumption in the technical fields of machines, vehicles, bridges, building structures, and the like, and has remarkable economic benefit and social benefit.

Description

technical field [0001] The invention relates to a vibration control device, in particular to a damper with variable damping coefficient used for reducing vibration and energy consumption of mechanical equipment, elevators and building structures. Background technique [0002] Damper is a widely used basic component of vibration control, which is used for vibration reduction, buffering and energy dissipation of machinery, vehicles, bridges and building structures. The common damper is a hydraulic cylinder type. The piston only moves in the axial direction relative to the cylinder. It is called a single-axis damper. It is composed of a moving body, a moving body rod, a cylinder body and a seal. The moving body is generally cylindrical. The moving body is provided with a number of small holes or an appropriate radial gap is left between the cylinder and the moving body. When the moving body moves relative to the oil cylinder, the liquid sealed in the moving body cavity on the ...
